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 9):
The power supply ripple rejection method according to  claim 7 , wherein the inductance of the first inductor used is less than or equal to 470 \u03bcH, and setting that a square of a ratio of an inductance of the second inductor to an inductance of the first inductor is equal to a coupling coefficient of the first inductor and the second inductor.
