A three-phase (or single-phase) AC input is rectified and filtered through an AC-DC converter, utilizing a high-frequency DC-DC conversion circuit composed of Insulated Gate Bipolar Transistors (IGBT) or MOSFETs. This circuit undergoes high-frequency (approximately 10-40kHz) transformation and regulation, followed by an efficient rectification and filtering process to convert it into a DC power supply suitable for the user's needs.
The control system employs fully digital DSP control, integrating multiple functions such as auxiliary power circuit, input/output sampling circuit, PWM generation, communication interface circuit, and protection circuit. It boasts high control accuracy and stability, rapid response speed, excellent anti-interference performance, comprehensive protection system, and rich communication interfaces.
