This paper proposes and examines a sinusoidal pulse width modulation (SPWM)-based single-phase diode clamped multilevel inverter for generation of multilevel output voltage. The SPWM signals and digital square pulses are generated using a single PWM module and I/O port of a PIC microcontroller. The performance of the proposed method is checked through simulation after the design of a diode clamp multilevel inverter for 3-level, 5-level, and 9-level output voltage. The 5-level and 3-level output have also been produced by hardware implementation of the designed circuit. Total harmonic distortion (THD) for 3-level, 5-level, and 9-level output voltage waveforms are analyzed.
