具有快速短路保护的1140V/90kW中频电源的研制

Development of 1 140 V/90 kW Mid-frequency Power Supply with quick Short Circuit Protection

介绍了1140V/90kw中频电源的研制。该电源输出电压在200～1500V之间连续可调,频率在250～1000 Hz之间连续可调。样机已转化成产品,该产品经受过多次短路试验的考验。

The development of the 1 140 V/90 kW mid-frequency power supply is introduced. The output voltage can be controlled from 200 V to 1140 V sequentially and the frequency can be controlled from 250 Hz to 1 000 Hz sequentially. The sample set has been turned into the products already. These products have passed the test of short circuit several times.
