Abstract

The power amplifier is a primary component in the control system of the magnetic suspending flywheel, which has to supply the electromagnet coil current proportional to an input voltage signal to generate the required magnetic field force. In this paper, a Pulse Width Modulated (PWM) switching power amplifier with a necessary Proportional Differential (PD) correction circuit is designed for the control system of the magnetic suspending flywheel. The experimental result shows that PWM power amplifier with PD correction features high efficiency, low signal distortion, broad bandwidth, and wide linear range and can meet the requirement for the control system of the magnetic suspending flywheel.
