[0002] The power regulator is a panel-mounted power adjustment unit that uses thyristors (also known as thyristors) and their trigger control circuits to adjust the load power. More often, digital circuits are used to trigger thyristors to achieve voltage and power regulation. Voltage regulation uses phase shift control, and power regulation has two modes: fixed-cycle power regulation and variable-cycle power regulation. The power regulator is an indispensable control component in industrial electric heating systems, especially in industrial automation systems as an important component for controlling load power changes. It can adjust purely resistive industrial loads through phase shift triggering and zero-crossing triggering to achieve the purpose of temperature control.
