SF280 Series Medium High Frequency Inverter Power Supply Control Board

Suitable for medium high frequency inverter power supply over then 100kW. Double DSP + CPLD control. Can be used for IGBT power supply, high frequency electroplating rectifier.

Product introduction:
The inverter power supply module adopts the latest power technology and digital DSP control, it is designed for new energy. The front stage adopts industry-leading three-phase active power factor correction (APFC) technology, and the latter stage adopts three-level full-bridge resonant soft switching technology. The input voltage range is wide, the total harmonic current is less than 3%, and the input power factor is up to 0.99. Efficient, high power density, high reliability. It adopts forced air cooling to dissipate heat, which occupies a small space and easy to assemble!

◆ Ultra-wide output voltage range: 200V~500Vdc;
◆ DC/DC conversion adopts full-bridge phase-shift soft switching technology;
◆ Adopt the world's leading active power factor correction (APFC) technology, input current total harmonic distortion THDI≤3%;
◆ High power output: 15KW, high power factor output: ≥ 0.99 full load;
◆ The DC output has an anti-backflow device to prevent instantaneous high current at the output of the charger when the battery pack is connected;
◆ Input and output adopt full isolation technology;
◆ Perfect protection and warning function, noise voltage warning, short circuit protection, fault warning;
◆ Support hot swap function;
◆ Fully digital DSP/DSP dual-core processor, supporting CAN2.0 bus communication function;
◆ Support voltage regulation, current limiting and current sharing functions;
◆ Support input over/under voltage protection, input over current protection (use with air switch), input three-phase unbalance protection;
◆ Support output over voltage protection, output over current protection, output short circuit protection, phase loss protection, over temperature protection, total       harmonic distortion;
◆ The voltage rating, insulation rating, and EMC are in line with my country's relevant technical standards for electric vehicle chargers
