Description
A control scheme for a high-density multi-channel regulated current power supply based on a compact high-speed PLC is proposed. This scheme adopts a hybrid analog-digital dual-loop control method. The power modules utilize mature commercial modules with built-in analog voltage control loops, while a single PLC constructs the current feedback loops for multiple power modules.
The scheme has been successfully applied to multi-channel focusing coil power supplies in an accelerator, featuring extremely high power density, simple interlocking and communication interfaces, and high operational reliability.
