摘要： A magnetic field energy harvesting device (200) includes an inductor (210) and a controller (220). The inductor comprises two inductor windings (210.1, 210.2) connected to each other in series, configured in winding directions and orientations to generate two voltages relative to the middle tap of inductor and out of phase with each other. The controller (220) switches the two voltages and generates an approximately constant DC output voltage (Uout) at an output capacitor (290) by alternating switching on and off switches (270.1, 270.2).

摘要： A timing controlled converter for converting a time varying input signal to a regulated DC output voltage for application to a load circuit. A feedback loop is employed as a control means for switchably coupling the time varying input signal to the load circuit for controlled periods of time in a manner so as to provide an average load voltage equal to a reference voltage. The duration of the controlled periods of time is a function of: the difference between the time varying input signal and the output voltage; and the integral of the difference between the output voltage and the reference voltage.

摘要： A rectifier circuit is disclosed comprising input terminals adapted to receive an alternating current voltage,and output terminals adapted to provide an output having a rectified output voltage. The rectifier circuit has a diode bridge in which the diodes are each adapted to be by-passed by a low-impedance path on activation of an associated electronic switching device (Q1,Q2,Q3,Q4). Furthermore, the rectifier circuit is adapted to control activation of one or more electronic switching devices(Q1,Q2,Q3,Q4), such that the flow of current relative to one of the output terminals is in one direction only.

摘要： Embodiments of the present invention provide novel techniques for using a switched converter to provide for three-phase alternating current (AC) rectification, regenerative braking, and direct current (DC) voltage boosting. In particular, one of the three legs of the switched converter is controlled with a set of pulse width modulation (PWM) control signals so that the input AC phase having the highest voltage is rectified and one of the switches in the two other legs is turned on to allow for added voltage. This switching activity allows for voltage from multiple AC line mains to be combined, resulting in an overall boost of the DC voltage of the rectifier. The DC voltage boost can then be applied to the common DC bus in order to ameliorate voltage sags, help with motor starts, and increase the ride-through capability of the motor.
