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 power inverter, such as a synchronous buck power inverter, that is configured with a high frequency switching control having a (PWM) controller and sensing circuit. Controller provides a low frequency oscillating wave to effect switching control on a synchronous-buck circuit portion that includes a plurality of switches to invert every half cycle of the frequency provided by controller. The inverting process thus creates a positive and negative transition of the oscillating wave signal. A low frequency switching stage includes a further plurality of switches configured to operate as zero voltage switching (ZVS) and zero current switching (ZCS) drives Charge on an output capacitor is discharged to zero on every zero crossing of low frequency switching stage and advantageously discharges energy every half cycle. During this discharge of energy, the zero crossing distortion in the low frequency sine wave is greatly reduced.

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.
