A novel method of synchronized PWM has been applied for flexible control of dual neutral-point-clamped inverters for photovoltaic installations. Algorithms of synchronized PWM provide continuous phase voltage synchronization for any operation condition of the system. Simulations show the behavior of a dual-converter-based photovoltaic system with three basic versions of synchronized PWM with low switching frequencies.

Abstract
A novel method of synchronized PWM has been applied for flexible control of dual neutral-point-clamped inverters for photovoltaic installations. Algorithms of synchronized PWM provide continuous phase voltage synchronization for any operation condition of the system. Simulations show the behavior of a dual-converter-based photovoltaic system with three basic versions of synchronized PWM with low switching frequencies.File in questo prodotto:
