DEFON Electronics Flyback Transformers – Reliable Power Conversion for Modern Applications

DEFON Electronics specializes in the design, development, and manufacturing of high-performance flyback transformers (also known as line output transformers) for a wide range of industries utilizing switch-mode power supplies (SMPS). Whether for AC-DC power supplies, DC-DC converters, or industrial power systems, our transformers deliver consistent efficiency, isolation, and durability.

How Our Flyback Transformers Work
A flyback transformer is a key component in a simple yet efficient switch-mode power supply. In a typical application, it works in conjunction with a primary switch, mutually coupled inductor, output rectifier, and input/output capacitors to regulate power flow.

The operation is straightforward:

• When the primary switch is on, energy is stored in the transformer’s magnetic core.

• When the primary switch turns off, the stored energy is released to the output, delivering current through the secondary winding.

• This process generates output voltages ranging from a few kilovolts up to 50 kilovolts, coupled with high-frequency currents typically operating between 17 kHz and 50 kHz.

This makes DEFON flyback transformers ideal for applications requiring high voltage generation in a compact form factor, such as:

• Power and electrical supply conversion

• AC-DC and DC-DC power conversion

• Converters and inverters

• Computers and PoE (Power over Ethernet) devices

• Motors, generators, and electrical pumps
