Overview:
SCR intermediate frequency power supply device, referred to as SCR intermediate frequency device, is a power supply device that uses the switching characteristics of SCR to convert 50Hz power frequency current into intermediate frequency current. It is mainly used in induction melting, induction heating, induction quenching and other fields. widely used in.
Its advantages are:

1. High efficiency
   SCR power supply device has a very high conversion efficiency (90-95%),
2. Small size and light weight
   The thyristor frequency conversion device is composed of semiconductor components. It has no complex mechanical rotating parts, no vibration, low noise, and no special requirements for the ground foundation during installation.
   3.Easy to operate
   The power adjustment range of the thyristor device is large. The frequency can change automatically as the load parameters change (so-called frequency tracking). The load loop is kept in a near-resonant state, which means it works in the best condition. In addition, it has a series of automatic protection devices, making its work stable and reliable.
3. Flexible startup
   SCR inverter devices generally adopt frequency sweep zero-voltage soft start, which has a high success rate of starting without impact, fast and stable.
