针对目前工频直流电动转辙机电源,提出一种利用高频开关电源技术研制的新型开关电源。该电源采用双管双正激变换技术、功率因数校正技术(PFC),实现了大功率高电压输出。详细论述了该电源模块的组成和工作原理。实际使用证明,该电源完全可以替代目前的工频电源。
In view of the current frequency DC electric point machine power supply, a new type of switching power supply developed by using high-frequency switching power supply technology is proposed. The dual-tube dual forward power conversion technology, power factor correction (PFC), to achieve high-power high-voltage output. The composition and working principle of the power module are discussed in detail. The actual use of proof that the power can completely replace the current power frequency power supply.
