Abstract :
A synchronization technique for static delta-modulated PWM inverters is presented. This control strategy removes the frequency modulation inherent in the delta-modulated inverter. Furthermore, synchronization of the PWM pulses with the reference signal ensures balanced phase voltages in three-phase applications. The performance of the modulator is analyzed using digital simulations and is verified with experimental circuits
