Operating Principle of MACS Module Power Supply
MACS module power supply adopts IGBT high frequency technology and the air cooling mode. MACS module power supply is provided with a DSP dual-core processor manufactured by Texas Instruments to communicate with the monitoring unit. The internal parameters can be set by the upper monitoring unit through a CAN interface or can be controlled by the upper monitoring unit. MACS module power supply adopts the soft switching technology, thereby having high efficiency and good electromagnetic compatibility; MACS module power supply has a built-in CPU control, thereby being stable and reliable and having ultra wide input voltage range. MACS module power supply has functions of input overvoltage and undervoltage protection, output current limit protection, output overvoltage protection, output short circuit protection, over-temperature protection and alarm, is connected with n + 1 modules in parallel and has the current sharing function.
