| Abstract: | In development of the power stage for a 2 kVA high frequency on line UPS,methods of anti parallel diode across the serial resistor and active clamps are adopted to reduce the gate voltage spikes over MOS gated inverter power switches during their turn off.Interference coupling path,operating principle and effect comparision of the corresponding measures are analyzed along with experimental confirmation. |
