Abstract :
This paper presents a new space vector PWM method for a 3-level flying-capacitor inverter. In the proposed technique, boundary restrictions can be easily incorporated to minimize the harmonic distortion of the output voltages. Simple algebraic equations are used to calculate the pulse widths of the gate signals from the sampled reference voltages. This feature make easy the implementation in real time. The voltages on the flying capacitors are regulated by simple ON-OFF controllers independently of the output voltage control. The main features of the proposed technique are analyzed by computer simulations. The experimental tests obtained confirm the expected results
