Operating Principle
The three-phase (or single-phase) AC input is converted through AC-DC rectification and filtering. The resulting DC power is then processed by a high-frequency DC-DC conversion circuit based on Insulated Gate Bipolar Transistors (IGBTs), MOSFETs, or other advanced power switching topologies. Through high-frequency conversion and regulation (typically 10–40 kHz), followed by high-efficiency rectification and filtering, the system provides a stable DC output power supply that meets the specific requirements of the end user. The control system adopts a fully digital DSP-based control architecture, integrating multiple functional modules, including:
- Auxiliary power supply circuits
- Input and output sampling circuits
- PWM generation circuits
- Communication interface circuits
- Protection circuits The system provides outstanding advantages including:
- High control accuracy and stability
- Fast dynamic response
- Excellent electromagnetic interference (EMI) immunity
- Comprehensive protection functions
- Rich communication interfaces
