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