    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.
