Research of the Physical Processes of the Power Electronics Device

The paper describes summarized equations describing physical processes in quasi steady and dynamic operation modes of the entire class of valve inverters (rectifiers, network driven inverters, converters and cycle-converters). MatLab calculations depict processes for a bridge joint with loads in AC/DC circuits. The paper also considers the dynamics of processes related to starting industrial RL-load through a reactor equipped rectifier within the direct current circuit. Those processes have been compared with RL-load starting by electrical devices. Practicality of the rectifier utilization with regards to starting production loads of alternate current is represented.
