The high-frequency switching DC power module employs a three-phase three-wire 380VAC balanced input, with no phase sequence requirements and no neutral current loss. At the AC input, it utilizes advanced peak suppression devices and EMI filtering circuits. The high-frequency switching DC power converts three-phase AC to DC via a full-bridge rectifier circuit, corrects the power factor passively (PFC), and then transforms the DC output into a stable and controllable DC via a DC/DC high-frequency conversion circuit. The pulse width modulation (PWM) circuit and the soft switching resonance loop of the high-frequency switching DC power automatically adjust the pulse width and phase shift angle according to grid and load changes, ensuring output voltage and current stability under any permitted condition. The power high-frequency switching power supply can operate individually to perform various basic functions and can also be combined in parallel for excellent load-sharing effects. Connected to a microcomputer, the high-frequency switching DC power module enables the four remote functions: remote measurement, remote signaling, remote control, and remote adjustment. Equipped with comprehensive protection functions, it ensures independent operation of the module or module group and system safety and stability under microcomputer monitoring. Avionics Power Supply
The high-frequency switching DC power module employs a bus sampling master-slave current sharing control method. During parallel operation, the module group can automatically select a master module, process external parameters such as current and voltage collected by the分流器, and centrally control the output voltage and current of each module. Consequently, even at low currents, a good current sharing effect can be achieved. 400HZ power supply
