PQ High Frequency Transformer

Super PQ High-frequency transformer is a power transformer whose working frequency exceeds the intermediate frequency (10kHz). It is mainly used as the high-frequency switching power transformer in the high-frequency switching power supply, as well as the high-frequency inverter power supply transformer in the high-frequency inverter power supply and the high-frequency inverter welding machine. According to the working frequency, it can be divided into several grades: 10khz-50khz, 50khz-100khz, 100kHz ~ 500kHz, 500kHz ~ 1MHz and above 1MHz. In the case of large transmission power, IGBT is generally adopted for power devices. Due to the phenomenon of shut-off current trailing behind IGBT, the working frequency is relatively low. Transmission power is relatively small, can use MOSFET, working frequency is relatively high
