Lighting electronic transformer

High frequency transformer is as the main switch power component parts. The switching power supply topology structure has a lot of. Such as half bridge type of transform circuit, the power work two switch transistor take turns to produce 100 kHz conduction of high-frequency pulse wave, and then through the high frequency transformer in variable pressure, the output transformer alternating current, all the windings of the circle number ratio is decided how much of the output voltage.

High frequency transformer is working frequency (more than 10 kHz) of intermediate frequency power transformer, mainly used for high frequency switching power supply of high frequency power transformers, also have used for high frequency inverter power supply and high frequency welding inverter in high frequency inverter power supply of the transformer. According to the working frequency height, can be divided into several levels: 10 kHz-50 kHz, 50 kHz-100 kHz, 100 kHz to 500 kHz, 500 kHz ~ 1 MHz, 1 MHz above.
