Switching power supply due to its state at high frequency inverter circuit

Large inductance and high charging rectifiers, bulky, cumbersome. And this power is the energy storage capacitor operating mode "is done and that charge" mode, thyratron and a high  electric meter  storage capacitor a  Electric transformer  the state, seriously affecting the thyratron and storage capacitor life. The switching power supply due to their work at high frequency inverter circuit, the transformer core is very small,  Circuit breaker  the need for large-scale energy storage capacitor coupled inductors and charge, therefore, small size, light weight. Switching power supply for the energy storage capacitor to adopt a "charging is completed, the release" mode, thyristors and capacitors to withstand high pressure of the time far below the resonant charging mode.
