Abstract
The present disclosure provides a control circuit and a control method of a bistable permanent magnet mechanism. The control circuit includes five switches, a diode and a control unit for controlling the five switches to be turned on and turned off. The control circuit enables the positive and the negative of the current passing through the coil to be adjustable at any time and avoids load breaking, without a complicated design of a driving circuit, thereby reducing the cost. It can also realize PWM control, adapt to a larger current range and different bistable permanent magnet mechanisms, and has a wide range of application scenarios.
