摘要
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 techniques, this paper designs an l l0KW variable frequency speed control system with 4-way output switching power supply for driving control circuit of the system and cooling fan. Experiment proves that the power supply can normally work and has good performance when output side and grid voltage have large fluctuation, and it can supply power for other electrical equipment.
