中频炉电源整流电路的负载是逆变器，逆变器输出有功功率是整流电路提供的，要求整流电路的直流输出电压在规定的范围内能连续平滑可调(0-513v)。中频电源的负载变化很大，整流电路应自动限制输出电压。通常是采用在负载端取出电流、电压信号来改变整流移相控制角，来完成截流、截压。
The load of the intermediate frequency furnace power supply rectifier circuit is the inverter, and the active power output of the inverter is provided by the rectifier circuit. The DC output voltage of the rectifier circuit is required to be continuously and smoothly adjustable within the specified range (0-513v). The load of the intermediate frequency power supply varies greatly, and the rectifier circuit should automatically limit the output voltage. Usually, current and voltage signals are taken out at the load end to change the rectifier phase shift control angle to complete current and voltage cutoff.
要求整流电路应对系统进行过电压和过电流保护，中频炉采用移相控制角=150度使直流输出负压形成有源逆变。直流电抗器是有源逆变的一个重要条件，大部分泥杆 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修  托辊生产线中频电源采用三相全控桥式整流电路。因为它的输出电压调节范围大而移相控制角的变化范围小，有利于系统的自动调节，它输出电压的脉动频率较高可以减轻直流滤波环节的负担。
The rectification circuit is required to provide overvoltage and overcurrent protection for the system. The intermediate frequency furnace adopts a phase shift control angle of 150 degrees to form an active inverter for the negative voltage output of the DC. DC reactor is an important condition for active inverter, and most intermediate frequency power supplies use three-phase fully controlled bridge rectifier circuits. Because its output voltage regulation range is large and the change range of phase shift control angle is small, it is conducive to the automatic adjustment of the system. The high fluctuation frequency of its output voltage can reduce the burden of the DC filtering link.
