The operation of unipolar and bipolar PWM techniques for Sine PWM (SPWM) and Third Harmonic Injection PWM (THIPWM) are studied for a single-phase H-bridge inverter. Total Harmonic Distortion (THD) is considered as the main performance parameter for evaluating various PWM methods.
Abstract: This paper presents a comprehensive performance study of different carrier-based pulse width modulation (CBPWM) methods for a single-phase H-bridge inverter. The operation of unipolar and bipolar PWM techniques for Sine PWM (SPWM) and Third Harmonic Injection PWM (THIPWM) are studied for a single-phase H-bridge inverter.
Also, the use of the technique of PWM further reduces distortion of the output voltage. Figure 4.14. (a) Line-to-line output voltage of a full-bridge inverter for switching in square wave mode. (b) Phase to neutral voltage in the same situation (a).
To overcome the disadvantages of the square-wave PWM, another modulation technique is used for controlling the full-bridge inverter. This method, which called the sinusoidal PWM, will enable the control of the AC output voltage and improve the harmonic performance of the inverter.
