ШИРОТНО-ИМПУЛЬСНОЕ РЕГУЛИРОВАНИЕ РЕЗОНАНСНЫХ ИНВЕРТОРОВ

Abstract

The article proposes a resonant voltage converter and methods for pulse-width regulation of its output voltage. The reasons for the inefficiency of regulating the output power of thyristor inventories are considered. The advantages of regulating resonant inverters with a closed input based on asymmetric cells are also described. In the course of this study, the scheme of a simple asymmetric inverter on a thyristor with a counter-parallel diode is considered. The results of a study of two pulse-width power control methods for resonant inverters in a DC circuit, as well as their main characteristics, are presented. The control characteristics were studied using a mathematical model of a resonant inverter containing two specified cells operating at a common load. The calculation was carried out by integrating a system of differential equations, and as a result of the calculation, the main characteristics of the inverter were obtained with two control methods. As a result of the study, possible options for using the considered methods of regulation are presented.
