High Frequency Switch Rectifier Module

Xuji ZZG22A- 40110 high frequency switch rectifier module

1. The full-bridge phase-shift resonant soft switching technology is adopted to greatly reduce the heat generated by the switch tube, and the working temperature rise of the rectifier module is greatly reduced, with an efficiency of more than 94%; the soft switching working mode reduces the electrical stress on the switch power tube, making the operation safer and greatly improving the reliability of the rectifier module.

2. Three-phase three-wire voltage input, three-phase current balance. Combined with the application of power factor correction technology PFC, the input current of the rectifier module is close to a sine wave, which greatly reduces the pollution of harmonic components to the power grid and has good electromagnetic compatibility (meeting the requirements of standard GB/T19826-20 for electromagnetic compatibility).

3. The application of low-voltage difference hardware autonomous current balancing technology can enable multiple parallel modules to bear the load current on average and extend the life of a single module. The current balancing function is realized by using the hardware of the module itself, with fast current balancing speed and high precision, and the current balancing effect is not affected when the monitoring module fails to exit.

4. The self-cooling series modules adopt an integrated connector structure and fully support hot plugging, so that the rectifier module can be freely plugged and replaced online without cutting off the AC power supply, making maintenance more convenient and quick. At the same time, the module shell adopts a high-grade aluminum-zinc plate composite structure, which is naturally cooled, noiseless and dust-free.

5. The air-cooling series modules adopt a unique fully isolated dust-proof structure. The airflow with dust can only pass through the isolated air duct. At the same time, the printed circuit board of the module is specially sprayed, which has the functions of corrosion resistance, mildew resistance and dust resistance, and the working reliability is greatly improved.

6. A single module is fully functional, with automatic voltage and current stabilization, output voltage and current setting, unlimited current regulation, operating status indication, output voltage and current display, input overvoltage, undervoltage, and phase loss protection, output overvoltage and overcurrent protection, power module overtemperature protection, and temperature-controlled fan automatic speed regulation (air-cooling series modules).

7. The distributed control working mode that does not rely on upper monitoring is adopted. Under normal circumstances, the rectifier module is controlled by the upper monitoring; when the monitoring module exits abnormally, the rectifier module automatically enters the safe working mode and operates according to the pre-set floating charge voltage value, so that the entire system can still work normally.
