Abstract

The invention discloses a charging device which comprises an AC-AC (Alternative Current-Alternative Current) conversion module, a resonance capacitor, a transformer, a rectification module and a sampling control module, wherein the AC-AC conversion module comprises a first switch tube, a second switch tube, a first driving unit and a second driving unit; the first switch tube is connected with the first driving unit; the second switch tube is connected with the second driving unit; primary coils of the resonance capacitor and the transformer are connected in parallel; the rectification module is connected with the transformer; the sampling control module is connected with two ends of the resonance capacitor, the rectification module, the first driving unit and the second driving unit respectively; and the sampling control module is used for generating control signals according to sampled voltage signals at two ends of the resonance capacitor and direct-current voltage signals output from the rectification module so as to control the first switch tube and the second switch tube. By virtue of the charging device, the structure and the procedure of a conversion circuit are simplified, and the electric energy transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a charging device. Background technique [0002] Most of the current charging circuits, DC-DC conversion circuits, and switching power supply circuits first convert the alternating current rectification into pulsating direct current (AC-DC), then filter, and then convert the direct current into high-frequency alternating current (DC) through the switching circuit. - After AC and power factor correction (PFC (Power Factor Correction), the high-frequency AC is passed through a high-frequency transformer, and then the high-frequency AC is rectified into DC, that is, AC-DC, and finally filtered to adjust and stabilize the voltage. [0003] From the above, it can be seen that in the prior art, the charging circuit needs to go through four processes, which not only has a complex structure but also causes a certain energy loss every time the electric energy flows through a p...
