Summarize the tips for improving the efficiency of lighting drive power during this time:
1. The main current loop PCB is as short as possible.
The experience and layout of LAYPCB, this is nothing, the quick way is to look at the works of Dachang.
2. Optimize the transformer parameter design to reduce the eddy current loss caused by ringing.
This is more difficult. First of all, we must master the basic knowledge of electromagnetics and design a reasonable transformer. The most important thing is patience. Even if we think of improving the efficiency by 0.5%, we must try it.
3. Reasonable selection of switching devices.
This is the balance between cost and performance, what kind of customer requirements, what kind of device to use, but reasonable. If you want efficiency, there is no doubt COOL MOS, low VF output diode
4. Input EMI part optimization design
If you have passed the safety regulations, this part is more studied, mainly the experience.
5. Choose a highly efficient topology
This is the beginning of the selection of the program, such as PWM and QR PFM. Currently, the customer is asked for the efficiency requirement, and it is necessary to evaluate what kind of topology is selected.
6. Choose a good electrolytic capacitor
Many people have neglected this, and the loss of electrolysis is very large. Teacher Chen Yongzhen has a detailed explanation in an article.
7. Start part of the power design
Under the premise of efficiency, it is necessary to consider that many chips currently have HV start pins, and the starting current is also getting lower and lower. This is to know more about the new devices. Of course, there are also non-destructive startup of external circuits. I think Not suitable for LED drivers.
8. Chip-assisted power supply optimization
This point of the L6562D application document pointed out that 15V is the best, but the LED is generally a wide voltage output, so my choice is to add a linear regulator, so that the chip works at 15V to reduce losses.
Battery Contacts
What is Battery Contact?
A battery contact is what connects the battery itself to an electrical circuit.
Battery contacts vary in shapes and sizes, depending on what type of battery. A typical battery has two connections: the positive and the negative.
Moreover, it is only proper that a battery contact has two terminals. Battery contacts have developed to be one of the most electrical components.
What is the function of a battery contact?
Battery contacts vary in shapes and sizes, depending on what type of battery. A typical battery has two contacts: the positive and the negative.
The circuit or load wouldn`t work with the battery without a battery contact.
Think about how a bridge connects two areas. The battery contact serves as a bridge here. It links the battery with the circuit (or whatever the battery sends power).
Remember, a battery has both positive (+ve) and negative (-ve) terminals. These terminals must create a firm contact with the circuit or load.
The construction of battery contact
In constructing a battery contact, we`ll take into consideration the following factors;
The size of the battery: Remote batteries are smaller. It makes the difference from batteries for computers. Thus, a bigger battery will need a more considerable battery contact. If a least tiny battery contact was of use, there is bound to be a loose contact.
The type of load the battery would supply power: For example, the remote-control battery`s shape is small. It is because the remote only needs a small amount of energy. Load that requires larger batteries uses more oversized battery contacts. Also, the battery contacts would need better connectivity.
The position of the battery: Batteries can either be surface mounted or in-built. It`ll affect the method of construction of the battery contacts. Battery contacts are not interchangeable. Here`s why the mounting position is an integral part of design planning.
Note the positive (+ve) and negative (-ve) sides of the battery: Damage to the load is non-negotiable when both terminals are not placed well,
You can then proceed to choose the right shape and size of battery contact.
Then select a suitable material of your choice. The type of material chosen would help you predict durability. It will also help you expect if you would deal with corrosion in the future.
Depending on the type of material you chose, you`d then make metal stampings.
At this point., take care to make sure you`ve concluded on your design pattern. The stamping process is irreversible. The process involves cutting the metals to the desired shapes and sizes. Thus, you would not want to waste resources in case of a failed design pattern.
After stamping, then you can plate the materials. Plating involves the process of adding other metals for the desired performance.
Battery contact can be made of which metals?
Generally, materials used in making battery contact have different properties. The components are nickel-plated, copper alloys, and carbon steel. Depending on the type of contact used, battery contacts use various materials. These materials include:
Nickel-plated
This material is for battery contacts to prevent corrosion of the connections.
Steels
This material, when mixed with chromium and nickel, gives a strong resistance. The idea of this mixture is to achieve two things. The anti-corrosion quality of nickel and the strength of the steel is. It makes it one of the most expensive battery contacts.
Gold plate
Gold plate is better for environmental ruggedness. It can withstand almost all environmental conditions.
Beryllium copper
This is one of the best properties for making battery contacts. Beryllium Copper contains 2% of Beryllium that provides its strength. It also includes 98% of Copper for its electrical conductivity. This material, when heated, becomes very tough. It makes it withstand high stress. Beryllium Copper is for harsh conditions. It is also non-magnetic, which makes it suitable for wide use.
Phosphor bronze
Phosphor Bronze functions where strength matters for battery contacts. It also withstands corrosion and possible future wear. It also possesses one of the best conductivity levels. The material is by far one of the best when reliability is essential.
Brass
You can mix brass with a host of other materials. Depending on the fabric it is mix with, it may appear so tough. The materials include; phosphorus, nickel, tin, chromium, aluminum, lead, etc.
Gold
This is one of the best metal conductors. Gold works well for battery contacts due to its high metallic conductivity.
Silver Plating
This metal has high electrical conductivity and conducts heat better. Although the surface gets rough with ease, it is easier to maintain. Silver is also easier to solder compared to other metals used in plating. It is also an excellent anti-rust material for battery contacts.
Tin Plating
This material offers ease of stamping as it is soft and can get cracked with ease. Moreover, it is non-toxic and an excellent electrical conductor. Tin serves as a good anti-corrosion for producing battery contacts.
Copper Plating
Copper plating offers a wide variety of applications. They are to coat other metals like aluminum and Beryllium. They are soft, malleable, and easy to solder too.
Zinc Plating
If corrosion is a significant problem, then you need zinc in your production. Zinc has a record of dealing very with corrosion.
Different battery contact types
Surface Mounted Battery Contacts
This type consumes less space. They are on the exterior part of the gadget. It as well gives room for ease of installation in case of maintenance.
Cylindrical and Spring Battery Contacts
This type of battery contact is in the gadget or equipment body. It offers a designated compartment for the batteries and saves space too. Television remotes and walkie-talkies are examples of this type of contact. These types of contracts allow tremendous versatility to consumers. They provide firmness for batteries.
PC battery contacts
As the name implies, these battery contacts are for PCs. The design varies from brand to brand. Although, they`ll keep their peculiar qualities. They also have dedicated battery compartments for them.
Enclosure battery contacts
This is an advancement of the spring battery contacts. This enclosure battery contact consumes less space. They are also easier to install. Due to their compact nature, they are being used for remote hand controls-their usage cuts across almost all walks of life. Examples are wristwatches, digital timers, car remote controls, etc.
How to use the battery contact?
The above outline has the types of battery contacts above. How to use battery contacts depends on what you want to achieve.
Cylindrical or spring battery contacts. These are best for a gadget that has designated battery space. It`s cheap and can adjust with the different lengths of batteries. This type offers low resistance on contact with the battery.
Surface Mounted battery contacts are best for gadgets with no designated battery casing. This type is essential to achieve high spring tension. Also, it has low connection resistance. I prefer this type whenever I design small circuits on printed circuit boards (PCBs). The surface-mounted battery contacts allow me to change my design when there is a need for it.
Coin Cell Enclosure gives you to be immersed in use even with smaller gadgets. This type is for lower power gadgets. The battery used is often smaller compared to Others.
PC Battery contacts, as the name implies, they are for PCs.
