摘要: A charging system utilizing energy storage multiplication is provided. An energy storage battery pack of the charging system is directly connected to a DC power transmission bus. When the charging request is initiated by the charging device, the charging device takes the power from the DC bus, the AC-DC converter and DC-DC converter connected to the energy generation device work as the energy source to deliver power to the DC bus, the power goes through the DC bus to the charging device, and the rest of the power goes to the energy storage device or goes out form the energy storage device when the charring power is higher than total energy from all other converters. The high C rate discharging of the energy storage device means high power capacity during discharging, this can provide much high power than AC-DC converter to fulfill the requirement of charging device.

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.
