Micro-controlled Pulse Width Modulator Inverter for Renewable Energy Generators☆
2014
Abstract A new controller for pulse-width modulation (PWM) inverter based on a circuit integrating a microcontroller and a symmetric output stage composed of two switching transistors which operate as switches for PWM has been developed. A model of operation was developed followed by the simulation and the realization of a prototype. The inverter output is filtered and a pure sine wave signal was generated. The PWM inverter adopting this PWM technique shows a simple method allowing to obtain pure sinusoidal output signal. In the context and framework of renewable energy, when associated in a generator architecture based on an intermediate HVDC bus, it is appropriated for a wide-range of power systems and applications.
