Abstract
The present invention provides a buck converter with single stage. The buck converter includes a buck device, a semiconductor component coupled to the buck device, a first resonance circuit coupled to the semiconductor component for adjusting operation time constant, and a second resonance circuit coupled to the first resonance circuit for suppressing ripple. The present invention controls the actuation time of circuit architecture change through LC resonance circuit timing means, automatically changes circuit architecture without active element, is balanced automatically without control energy, and simplifies circuit design. The present invention is characteristic of negative voltage source, which overcomes problems of load voltage potential barrier, and realizes a circuit design of sharing the energy storage and the filtering elements, so as to achieve fast input response, low output ripple and long service life.
