Abstract

The invention discloses a three-phase Ac-DC non-contact power supply system with a power factor correction function. Three channels of single-phase alternating current are respectively rectified to unidirectional pulsating direct currents via a single-phase full bridge rectification circuit, high frequency alternating current is obtained via the chopping of the three pulsating direct currents, electric energy is transmitted from primary coils to secondary coils, three secondary coils are respectively connected with a capacitor in parallel to form current sources, the three channels of current sources respectively output energy to a voltage-doubling rectification circuit to form three channels of charging pump circuits, output terminals of the three channels of charging pump circuits are connected in parallel, a unified direct current voltage is obtained, and stable direct current voltage can be obtained by employing a secondary filtering circuit. According to the system, the work is reliable, and the power supply efficiency can reach more than 90% to the maximum.

Description

technical field [0001] The invention relates to the technical field of non-contact power supply and automatic control, in particular to a three-phase AC-DC non-contact power supply system with power factor correction function. Background technique [0002] Traditional non-contact circuits generally adopt a DC-DC structure. Research on non-contact power supply technology focuses on the realization and control of DC / DC conversion circuits. This circuit is usually powered by AC low-voltage mains power (220V / 380V). An AC-DC power factor correction circuit is added between the power supply and the DC-DC non-contact circuit to convert alternating current into direct current for use in the DC-DC non-contact circuit. The AC-DC power factor correction circuit needs to add an additional set of control circuit, detection circuit and converter circuit, making the circuit more complicated. The AC-DC non-contact power supply system only needs a set of control circuit, detection circuit a...
