Abstract
The switching mode DC voltage converter controlled by the integrated voltage control method works stably and has no steady state error. The basic circuit of this control method consists of an error voltage integrator and a hysteresis comparator which drives a power transistor to on/off. In this paper，we propose a new AC voltage PWM converter circuit controlled by the integrated voltage control method. There are four operational quadrants on the voltage-current plane in this new AC voltage converter. Four power transistors arc controlled by the four hysteresis comparators driven in parallel by one error voltage integrator. It is possible to connect an R-L load of which the voltage phase and the current phase are different. It has been confirmed that the new AC voltage converter has no steady state error and a quick response time，although the control circuit is simple.
