Abstract: Introduction was made to the using plan and control method of present domestic high-voltage permanent magnet circuit breaker commonly used for breaking and making coil power. The defects of this method were indicated. A kind of plan was designed based on DC screen power and pulse width modulation (PWM) control. This plan has eliminated the defection in domestic energy storage capacitor in common use, enabling breaking and making control more smooth and saving product cost.
Key words: permanent magnet circuit breaker; DC screen; pulse width modulation; movement control; controller
