基于PWM控制技术设计了一款110kW变频调速系统用4路输出开关电源,可为变频调速系统驱动控制电路及散热风扇供电。试验证明,在电网电压及输出侧有很大波动情况下,该电源仍能正常工作、性能良好,并同时可为其他电气设备供电。
Based on the PWM control technology, a 110kW inverter speed control system with 4 output switching power supply can be used to drive the control circuit and the cooling fan. Test proved that, in the grid voltage and output side has a great deal of volatility, the power supply can still work normally, good performance, and at the same time for other electrical equipment.
