• The most advanced adaptive resonant full-bridge PWM control IC, with adaptive zero voltage delay control function, supported by efficient resonant inductor, so that the IGBT can almost achieve ZVS in the whole working conditions, reduce the loss of IGBT by 40%, while improving EMC characteristics, reduce the interference to the power grid and power itself.
• The selection of uHF low saturation voltage drop of high power and high voltage IGBT, so that the third generation of switching power supply working frequency than the second generation of switching power supply working frequency is higher, reduce the size of magnetic materials; At the same time, the low saturation drop reduces the loss of IGBT.
• Original stable, no reaction delay time hot backup technology, multiple machines with the same frequency and phase parallel work when a unit machine in the system fails, the rest of the unit function in a very short time to make the total output current to set and stable (time <30 ms).
