  • METHOD OF DYNAMICALLY CONTROLLING MINIMUM DUTY CYCLE AND RELATED HALF-BRIDGE BOOTSTRAP CIRCUIT
    Publication number: 20210320649
    Abstract: A half-bridge bootstrap circuit includes a high-side switch, a low-side switch, and a boot capacitor. A dynamically controlled minimum duty cycle curve is adopted to guarantee the minimum turn-on time of the low-side switch so that the boot capacitor can be sufficiently charged for keeping the high-side switch in the turn-on state. Also, the value of the minimum duty cycle curve can be dynamically set according to different operational phases of a load, thereby increasing the maximum output power of the load.
