    摘要： The disclosure provides a single-stage isolated bidirectional converter and a control method thereof. The converter includes: a first full-bridge circuit unit, a half-bridge circuit unit, a second full-bridge circuit unit, a phase-shift inductor unit, a transformer and a filter capacitor. The transformer includes a first winding and a second winding, and the first winding is provided with a center tap. The center tap is connected to the first port, two ends thereof are connected to the midpoints of the two bridge arms of the first full-bridge circuit unit through the phase-shift inductor unit, and two ends of the second winding are connected to the midpoints of the two bridge arms of the second full-bridge circuit unit. Two ends of the first full-bridge circuit unit are connected to two ends of the half-bridge circuit unit; two ends of the half-bridge circuit unit are connected to two ends of the filter capacitor.

    摘要： A three-phase single-stage isolated bidirectional converter and a method of controlling same are provided. The bidirectional converter includes a three-phase AC voltage port, a DC voltage port, full-bridge circuit units, half-bridge circuit units, phase-shift inductor units, transformers, and filter capacitors. The first full-bridge circuit unit is connected to the first half-bridge circuit unit. The third full-bridge circuit unit is connected to the second half-bridge circuit unit. The fifth full-bridge circuit unit is connected to the third half-bridge circuit unit. The first half-bridge circuit unit is connected to the first filter capacitor. A midpoint of a bridge arm of the first half-bridge circuit unit is connected to a second port. A midpoint of a bridge arm of the second half-bridge circuit unit is connected to a fourth port. A midpoint of a bridge arm of the third half-bridge circuit unit is connected to a sixth port.

    摘要： The disclosure relates to the technical field of charging, and in particular, relates to a charging apparatus. A charging apparatus includes a support unit; a charging bow lifted and assembled on the support unit; a retractable mechanism, where the retractable mechanism retracts a cable, and a free end of the cable pulls the charging bow up and down; and a straining member assembled on a mounting point of the cable near the free end. After the charging bow is docked with a pantograph, the retractable mechanism continues to release the cable to relax the cable. Under the action of the straining member, the cable between the mounting point and the retractable mechanism is in a strained state, and the cable between the mounting point and the charging bow forms a cable slack section.
