Abstract:
The invention provides a self-coupled power supply ripple rejection circuit and method, the circuit includes a coupled inductor, a balanced capacitor, an input capacitor and an output capacitor. The coupled inductor includes a first inductor and a second inductor coupled to each other and wound around a same magnetic core, a dotted terminal of the first inductor and one end of the input capacitor are both connected to a power supply input end, a dotted terminal of the second inductor is connected to one end of the balanced capacitor, and the other end of the first inductor, the other end of the second inductor and one end of the output capacitor are all connected to the power supply output end, and the other end of the balanced capacitor, the other end of the input capacitor and the other end of the output capacitor are all grounded. The invention adopts a special inductor—coupled inductor, cooperated with a balanced capacitor to achieve high reliability and high efficiency power supply ripple rejection. At the same time, the circuit volume is reduced, the circuit loss and the product cost are reduced, and the requirements of environmental protection and pollution-free are met.

Claim (Index 7):
A self-coupled power supply ripple rejection method, characterized in that a coupled inductor is arranged between an input end and an output end of a power supply, and the coupled inductor includes a first inductor and a second inductor coupled to each other and wound around a same magnetic core, an input end of the power supply connects to a dotted terminal of the first inductor, and the other end of the first inductor connects to the power supply output end, a dotted terminal of the second inductor is grounded through a balanced capacitor, and the other end of the second inductor is connected to the power supply output end; after the power supply is turned on, a voltage of the first inductor and an induced voltage on the second inductor are inverted, and the current that an input voltage of the power supply input end increases on the first inductor and the current that the induced voltage decreases on the second inductor interact with each other, offset to achieve AC ripple rejection.
