Simulation Results

Multi-level inverter can output high voltage directly and can be connected without transformer, so it is applied more and more widely in high power situation. This paper presents a cascade H bridge seven-level parallel active power filter. This paper analyzes the principle of cascade H bridge multi-level inverter, designs a cascade H bridge seven-level SAPF based on CPS-SPWM, and the principle and the effect are simulated. The simulation results show that this system can compensate load harmonic current.
