摘要： An improved power factor DC power supply in accordance with the present invention (100 or 200) employs a power factor correcting network (120), a full-wave rectifier means (122), a pair of filter capacitors (124 and 126), and three current steering diodes (128, 130 and 132). The power factor correcting network (120) includes both an inductor means (136 and 240) and a capacitor (138), the combination configured to improve the power factor DC power supply (100 or 200) presents to the AC power-line (102) by reducing the level of harmonic currents the DC power supply generates on the AC power-line. The filter capacitors (124 and 126) are configured with the current steering diodes (128, 130 and 132) such that the filter capacitors are charged in series and discharged in parallel. In addition, the filter capacitors (124 and 126) and the current steering diodes (128, 130 and 132) are configured such that during the periods when the level of the voltage being developed across the load (104) exceeds one-half the peak level, the improved power factor DC power supply (100 or 200) functions as though the filter capacitors were not in the circuit.

摘要： An arrangement for improving the power factor at the input of an off-line switching type power supply is operative to extend the duration of the pulse current conducted by the diode rectifiers. A parallel LC ringing circuit (413) is introduced between the AC line (401) and the rectifier (404) of the switching type power supply to enhance the voltage enabling conduction of the rectifying diodes and hence initiate current flow through the rectifying diodes earlier in each half cycle. This extends the conduction interval of the rectifying diodes significantly and enhances the power factor at the input to the switching type power supply.

摘要： Sampling of a control system that controls an inverter and updating of a command value are prevented from being degraded, even when the resonance of an LC filter is suppressed using a suppressing current. In a block 10a, a current distribution factor generator 11 receives an amplitude Vm of a single-phase AC voltage Vin, an amplitude Im of an input current, a command value Idc* of a DC current Idc, a command value Vc* of a both-end voltage Vc, and a power angular velocity ω, and outputs a current command value Ib*. A resonance suppression controller 15 receives a reactor voltage VL, and outputs a correction value k·VL. A subtractor 17 subtracts the correction value k·VL from the current command value Ib*, and provides the result to a chopper controller 16. The chopper controller 16 outputs a boost duty dl based on a corrected current command value (Ib* - k·VL). A comparator 14 compares the booster ratio dl with a carrier C2, and outputs the result as a control signal SSI.

摘要： An AC/DC converter includes a rectifier circuit and a power factor correction circuit. An input port of the rectifier circuit receives an alternate current. The power factor correction circuit includes a first inductor, a second inductor, a first capacitor, a second capacitor, a first diode and a second diode. An end of the first inductor electrically connects to a positive pole of an output port of the rectifier circuit, and the other end electrically connects to a ground terminal of the output port through two parallel series routes which are bridged by the first diode. Wherein a series route contains the first capacitor and the second diode, and the other series route contains the second inductor and the second capacitor. The second capacitor is provided for parallel connecting with a loading. In this way, the input current could be controlled to increase the power factor effectively.

摘要： A high-frequency ac-dc power converter takes an input ac signal and converts it to an output dc signal. The converter has at least two front-end rectifier diodes arranged as a full wave rectifier of the input ac signal. A first inductor positioned at the output of the full wave rectifier. An output capacitor is connected across a load for the converter. There are at least one additional inductor and one additional capacitor. A switching circuit selectively forms different (LC) resonant circuits with the inductors and capacitors during a cycle of the input ac signal to form a dc-dc power converter.
