Military field self-determination power supply technology is the key matter for weapon equipments to work in effect. With the development of invert technology and variety of power elements, it is possible for vehicle-based inverter to become less volume and more efficient.This paper is based on the simulation analysis of some typical invert circuit topology. Through the characters of vehicle-based inverter, the paper describes compensation methods of DC/DC converter. It puts forwards an adjust tache to compensate the zero point and the polar point. Besides these, the paper designs and makes a pulse-wave inverter. Combined with some problems in debugging, it puts most emphases on the factors which affect the efficiency of inverter; does some simulation and experiments analysis and gets a lot useful results. The paper gets a serious of significant results on how to improve efficiency of inverter such as the choice of switch parts, the choice of parameters of transformer design, and the adjustment of syntony capacitance and loop inductance, which offers better measures for later design of inverters under field operation conditions.
