The cascade-connected boost circuit includes a first-stage boost circuit, a second-stage boost circuit, an output terminal and a regulation filtering capacitor. The first-stage boost circuit includes an input terminal, a PWM generator, a first inductor and a first switch. The second-stage boost circuit includes a second inductor and a second switch. The PWM generator controls the first switch and the second switch to turn on or turn off simultaneously. A power supply from the input terminal respectively charges the two inductors via two paths when the two switches are turned on. The two inductors release energy when the two switches are turned off. The two switches share the voltage of the output terminal. The cascade-connected boost circuit according to the present invention solves the issues that the withstand voltage limit of a single switch and the limit of a duty cycle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cascade-connected boost circuit","description":"A cascade-connected boost circuit is disclosed.
