Sine inverter controller with 8 bit microcontroller

Abstract

This article describes the design of a sine wave inverter control unit. We will define the basic principles and requirements to control and maintain a good quality of inverter's output. The solution that can achieve full 8 bit output resolution with 10 bit measurement and regulation time shorter than mains period is proposed. Furthermore, the possibilities and ways of implementing the control unit using the 8 bit microcontrollers are described, so it is possible to gain a complete understanding of this issue.
