ABSTRACT:
A low-cost, completely adjustment-free current-controlled PWM inverter substantially solving the conventional problems associated with the gain adjustment of a current error amplifier is provided. The current-controlled PWM inverter comprises a motor current detector, a main circuit power controller, a current comparator, a timing signal generator, and a switching control signal generator configured such that the switching control signal generator sets the switching control signal to switch the main circuit switching power elements on or off at the refresh timing and at the timing at which the current comparison result state changes.
