Abstract
The present invention relates to an impedance source boosted/ reduced direct current/alternate current converter. The converter is composed of two one-way power electric switches, an X type unique resistance source network composed of an inductor and a capacitor, a direct current source and a load, wherein the two one-way power electric switches are respectively composed of a full control power electronic device. The booting and the reduction of output currents are realized by the high frequency switching work of the two one-way power electronic switches and the periodic charging and the discharging of passive elements of the impedance source network.
Description
Technical field:
The present invention relates to a kind of current mode DC to DC converter, is about output current infinitely variable DC to DC converter specifically.
Background technology:
For the application scenario of needs adjusting direct current, often adopt between the voltage-type DC to DC converter traditionally and fetch realization.Shortcomings such as at some occasion power supply itself is exactly current source, and traditional Power Conversion mode is just improper, and exists the Current Regulation scope little, and common-mode conducting or common-mode are turn-offed and all can be damaged power electronic device during the switch complementary conducting, and the EMI problem of circuit is serious.
The purpose of this invention is to provide a kind of novel DC to DC converter based on source of resistance converter thought, this converter circuit is simple in structure, the Current Regulation scope is big, and conducting of switch common-mode or common-mode are turn-offed all unlikely damage power electronic device, and direct current input side current harmonics is few.
Summary of the invention:
According to the foregoing invention purpose, the present invention proposes following scheme:
The impedance source up/down current DC to DC converter of this programme, its circuit comprises two unidirectional electronic power switch S1 and S2, a lattice network that constitutes by two inductance L 1 and L2 and two capacitor C1 and C2, DC current source and load, unidirectional electronic power switch S1 is series between source of resistance network and the load, unidirectional electronic power switch S2 is parallel between source of resistance network and the power supply, two unidirectional electronic power switch S1, S2 form by an all-controlling power electronics device, and two unidirectional electronic power switch S1, S2 are operated in the HF switch state.
The output current of this converter is recently to control by the duty of regulating described unidirectional electronic power switch S1 or S2, can be below or above input current.
This converter can be used for as the charge power supply of AC power, supplying power for photovoltaic cell distributed power source, superconduction power supply, supplying power for photovoltaic cell, heat exchanger system, induction heating power, induction motor drive system, nonmagnetic atom resonator system, vacuum arc ignition system, vacuum arc furnace system, current mode conveyer belt system, low noise detection system etc.
Impedance source up/down current DC to DC converter of the present invention comprises input filter, unidirectional electronic power switch, source of resistance network, output filter, power supply and load.Through the HF switch work of two unidirectional electronic power switches, the passive component of source of resistance network periodically discharges and recharges, and realizes the rising or the reduction of output current.
The present invention introduces unique source of resistance network, and circuit has extreme high reliability, and damages power electronic device can avoid conducting of two unidirectional electronic power switch common-modes or common-mode to turn-off the time.Because the operating frequency of electronic power switch is far above power supply and output voltage frequency, the passive component value of source of resistance network is very little, and the volume of entire circuit, weight are all less, the efficient height.
