Abstract: This paper introduces a combinational modulation method to be used in classic full-bridge single phase inverters. The proposed method eliminates even-order harmonics at PWM stage in control section unlike the conventional method of even order harmonic cancelation in power stage and offers a cost effective design by switching one leg at high frequency. Using a low cost Digital Signal Controller (DSC) platform, regular sampling technique based on real time calculation was employed to verify the feasibility of the proposed method on a 500W single phase Voltage Source Inverter. Performance characteristics such as switching losses and harmonic distortions are presented for the new approach and compared with a classic inverter modulation method.
