Abstract: A capacitor-drop power supply includes a rectifier and a switched capacitor converter coupled to the rectifier. The rectifier is configured to receive an alternating current (AC) signal at an AC voltage and convert the AC signal into a rectified direct current (DC) signal at a rectified voltage. The switched capacitor converter is configured to receive the rectified DC signal and generate a converter output signal at a converter voltage that is proportional to the rectified voltage and that is less than the AC voltage.

Abstract: A voltage proportional to a sum of currents flowing though first and second coupled inductors is developed across a first capacitor common to first and second series RC networks if the RC networks are time constant-matched to the inductors. The first and second inductors are coupled between a first and second switched drive phase input terminal, respectively, and an apparatus output terminal. The first and second RC networks are coupled in parallel with the first and second inductor, respectively. Inverting and non-inverting inputs of an amplifier are coupled to junctions of third and fourth time constant-matched series RC networks coupled in parallel with the first and second inductors, respectively. The amplifier subtracts voltages sensed at the junctions to generate a difference signal proportional to a magnitude difference of the currents flowing through the inductors.
Abstract translation: 如果RC网络与电感器时间恒定匹配，则与通过第一和第二耦合电感器流动的电流之和成比例的电压跨越第一和第二串联RC网络公共的第一电容器被开发。 第一和第二电感器分别耦合在第一和第二开关驱动相位输入端子和装置输出端子之间。 第一和第二RC网络分别与第一和第二电感器并联耦合。 放大器的反相和非反相输入分别耦合到与第一和第二电感器并联耦合的第三和第四时间恒定匹配串联RC网络的结。 放大器减去在结处感测的电压，以产生与流过电感器的电流的幅度差成比例的差分信号。
