    摘要: A regulator rectifier device and a method for regulating an output voltage of the same which takes input from three phase alternating current voltage generating device with each phase including a positive cycle and a negative cycle. A first rectifying unit with a first gate terminal, connected to the generating device to rectify the positive cycle of said three phase alternating current voltage. A second rectifying unit with a second gate terminal, connected to said generating device to rectify the negative cycle of said three phase alternating current voltage, wherein said second rectifying unit switches between rectification mode and shunt mode depending on the load condition. And a controlling unit configured to control said second rectifying unit by a gate control signal, said controlling unit outputs said gate control signal based on an output voltage of said regulator rectifier device with respect to a first predefined voltage in battery connected condition or third predefined voltage in battery-less condition and said positive cycle and said negative cycle of each phase of said three phase alternating current voltage from said generating device, said gate control signal enables said second rectifying unit to switch between rectification mode and shunt mode by controlling the second gate terminal of said second rectifying unit, wherein said gate control signal switches said second rectifying unit into shunt mode when the output voltage of said regulator rectifier device is greater than said first predefined voltage in battery connected condition or third predefined voltage in battery-less condition and thereby continuing the shunting of said second rectifying unit as long as said positive cycle of corresponding phase of said three phase alternating current voltage exists.

    摘要: A high-frequency isolation alternating/direct current conversion circuit and a control method thereof are disclosed. The conversion circuit includes an alternating current source (V1), a direct current source (V2), a direct current side synchronous switch (400), high-frequency isolation transformers (TRA, TRB), direct current side high-frequency inverter bridges (100, 200), resonant inductors (L2, L3, Lr), resonant capacitors (C3, Cr), a high-voltage energy storage filter (C), an AC-side inverter bridge, and an output filter (C2). Using a preset DC-side voltage as baseline, a circuit is switched between two operating modes of rectification and inversion according to an external voltage reference and by different open operating modes of the inverter bridge, and achieving soft switching by a resonant mode of a high-frequency inverter bridge topology, thereby reducing switching loss, facilitating an increase of operating frequency or an increase in efficiency of an inverter circuit, thus increasing power density and reducing volume. DC voltage inversion in a wide range is achieved by open timing control of the high-frequency inverter bridge, thus obtaining high efficiency in applications with wide voltage variation ranges such as batteries, etc.

    摘要: A wireless power receiver IC in which the power path can be reconfigured as either a low-dropout regulator (LDO), a switched-mode power supply (SMPS) or a power switch (PSW) is provided. All three modes share the same pass device to reduce die area and share the same output terminal to reduce pin. In an inductive wireless receiver, the power path can be reprogrammed on the fly to LDO or PSW mode or can be reprogrammed on the fly to SMPS or PSW mode. In a resonant or multi-mode wireless receiver, the power path can be reprogrammed on the fly to SMPS or PSW mode. Furthermore, to achieve high power transfer efficiency performance, using N-channel MOSFET as its pass device has better efficiency and smaller die area than P-channel MOSFET pass device.
