Adjustable Frequency Power Supply的用法和样例：
- The theory of low frequency power supply and the characteristics of lowfrequency power source generator are introduced.
- The medium frequency power supply of induction heating is one of solid state supplies which is composed of the high-power thyristors.
- The cause of intermediate frequency power supply havig lower power factor was analyzed, and the way of improving the power factor of the controlled rectifying device was proposed.
- It is an important energy saving measurement to adopt low frequency power supply technology in submerged-arc furnacesmelting ferroalloy, which, can make power factor improve10%--15%, bower consumption reduced8%, production increase10%.
