The load of the bridge rectifier circuit of the switching power supply
of medium-frequency electric furnace is the inverter power supply, and
the output power factor of the inverter is given by the bridge rectifier
circuit.
中频电炉开关电源桥式整流电路的载荷是逆变电源，逆变器輸出功率因素是桥式整流电路给予的，规定桥式整流电路的直流电输出电压在规范的范畴可以持续光滑可调式。
If
the load of the medium frequency induction furnace changes, the bridge
rectifier circuit should automatically limit the output voltage.
中频感应炉的负荷发生变化，桥式整流电路应全自动限定输出电压。
Usually,
IF electric furnace is selected to take off the current flow and
working voltage data signal at the load end to change the rectifier
phase shift control Angle to intercept and intercept voltage.
通常中频电炉是选用在负荷端取下电流量、工作电压数据信号来更改整流器移相操纵角，来进行截留、截压。
If
the furnace has another provision for the bridge rectifier circuit:
when the inverter power supply is operating incorrectly, if the furnace
can store the heat in the series reactor back to the DC power network
according to the bridge rectifier circuit, so that the inverter power
supply is maintained, that is, the digital power amplifier inverter
power supply.
中频电炉对桥式整流电路还有一个规定是：当逆变电源运作错误时，中频电炉可以把存储在串联电抗器中的热量根据桥式整流电路回到到直流电力网，使逆变电源获得维护，即数字功放逆变电源。
