Duty cycle of a circuit breaker
WebApr 24, 2016 · Power circuit breakers are equipped with a two-step stored energy mechanism to facilitate the opening or closing of the main contacts by stretching or compressing powerful springs. The two-step stored energy process allows for an open-close-open duty cycle, which is achieved by storing charged energy in a separate closing … WebSome gate drivers may not be able to operate at 100% duty cycle (e.g., if using a bootstrap capacitor in a high-side gate driver, the cap will eventually bleed down to 0V). You can generally run an IGBT continuously within its safe operating area - review voltage, current, and thermal ratings.
