This paper provides a comparative analysis of bipolar versus unipolar Sinusoidal Pulse Width Modulation (SPWM) in DC-AC inverters, focusing on Total Harmonic Distortion (THD) across modulation indices and the latter's effects on the R-L loads. Both SPWM strategies are implemented using. . Abstract— An inverter is needed when an electric load requires an AC power supply while the available one is a DC power supply. The quality of an inverter, one of which is determined by, among others, by the output waveform, whether a square wave, modified sinuses or pure sinuses. Among the three. . There are many inverter topologies but output current distortion and efficiency are the two main parameters for the selection of inverters. Two such topologies are described herein. In this paper, the SPWM (Sinusoidal Pulse Width Modulation) technique of unipolar and bipolar inverters is presented. . Two different switching strategies are used in Sinusoidal Pulse Width Modulation (SPWM) for controlling a single-phase inverter. A single sine reference signal is compared with a high-frequency triangular carrier. Output voltage swings between +Vdc and -Vdc. Only two levels, so more harmonics. The voltage at the input terminals is constant. controlled turn-on and turn-off. bridge or full-bridge configuration. The single-phase units can be joined to have. . The single-phase full-bridge inverter converts a fixed DC voltage into a controlled AC voltage. It consists of an input capacitor C and four switches (usually insulated-gate bipolar transistors (IGBT) or MOSFETS). When switches Q and will be equal. .
