发明名称 Drive Scheme for Weakly Coupled Coils
摘要 A variable efficiency and response buck converter is achieved. The device includes a multi-phase switch, the coupled coils, the filter capacitor, and the load. The multi-phase switch includes the phase control inputs, the circuit common reference, at least two pairs of complementary switches with each switch containing one upper switch and one lower switch, at least two phase control outputs from the complementary switches. The coupled inductive coils are coupled to the phase control outputs to enable weak couplings and strong couplings. Based on the working mode, equivalently the coupled coils can provide strong mutual inductances and weak mutual inductances. The filter capacitors connected to the output of the coupled coils provide high efficiency output to the load.

主权项 1. A switch converter, the device comprising: a multi-phase switch having an input voltage; mutually coupled inductive coils connected to the multi-phase switch; wherein the switching converter is capable of tuning the inductance of the mutually coupled inductor coils to provide a lower inductance for fast converter response or a higher inductance for suppression of current ripple.
