Design of Soft-Switched Inverter

Abstract:

In order to decrease the exhaust of the switch of inverter bridge arm, the auxiliary resonant net was imbed in the circuit structure which lead to cost ascension and credibility descend. This text discusses to design a DC/AC converter based on simplex single voltage source high frequency chain inversion technology, the output is 0.9KW/115V/400Hz.The pulse direct current voltage has been created by forward circuit and absorption branch which is controlled by voltage feedback in the input terminal of inverter bridge arm. The soft-switch of inverter bridge arm using DPM has been realized by controlling open or close of switch electric circuit on the invert bridge arm at pulse voltage for zero stages. It is not adding topology complicated degree of main circuit which could assure the reliability of the inverter.
