Abstract :
A fixed frequency current mode PWM modulator that provides output current limiting in sliding mode voltage controlled DC-AC power converters is presented. The modulator is considerably simpler than previous solutions and well adapted for sliding mode control, which is advantageous when the inverter feeds nonlinear or wide ranging loads and performs as a switching power operational amplifier or power operational transconductance amplifier
