EFD20 High Frequency Flyback TransformerA transformer commonly found in switching power systems and specifically designed for use in flyback power conversion topologies. It utilizes the EFD20 core shape, a design that excels in high-frequency and high-efficiency conversion for a wide range of applications requiring small, high-efficiency, low-cost power supplies.
1. Switching Power Supply (SMPS):
Flyback Power Supply: EFD20 High Frequency Flyback Transformer is
usually used in flyback switching power supply (Flyback converter).
These power supplies are widely used in consumer electronics, home
appliances, industrial control systems. Flyback power supply with
its simple structure, low cost, wide range of applications and
other advantages, commonly used in low-power and medium-power power
supply system.
Application examples: such as television power supply, audio
equipment, power tools power supply.
2. LED drive power supply:
EFD20 High Frequency Flyback Transformer is also widely used in LED
drive power supply. As LED lamps need stable current and voltage,
flyback power supply can provide efficient and stable power output
to ensure the normal operation of LED lamps.
Advantage: High-efficiency conversion of the flyback power supply
can improve the efficiency of the LED driver, extend the service
life of the LED lamps and lanterns, and is suitable for mass
production due to its low cost.
3. Battery charger:
In portable devices and consumer electronics, EFD20 High Frequency
Flyback Transformer is used in battery chargers, especially in
adapters and portable battery charging devices. Flyback
transformers are able to provide a stable output voltage to suit
the charging needs of different types of batteries (e.g. Li-Ion,
NiMH, etc.).
Application examples: such as smart phones, tablets, power tools
and portable electronic device chargers.
4. Power supply for power tools:
Power tools require efficient and reliable power supply, EFD20 High
Frequency Flyback Transformer can be used in chargers and battery
management systems for power tools. These transformers are suitable
for power tools that require stable and efficient power conversion.
Advantage: Due to its high efficiency and compact design, the EFD20
transformer is particularly suitable for power tool applications
with stringent size requirements and medium power demand.
5. Small inverters:
The EFD20 High Frequency Flyback Transformer is widely used in
small inverters such as portable power supplies or solar inverters.
Inverters convert DC power to AC power, and the EFD20
high-frequency flyback transformer provides efficient power
conversion and ensures stable system operation.
Application examples: e.g. portable solar panel inverters, portable
generators.
