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.
- This paper presents a hybrid control scheme based on repetitive control and multiple feedback loop control to improve both the transient and steady-state responses of a single-phase CVCF PWM inverter used in 400Hz medium frequency power supply.
