Abstract
In one embodiment, a bidirectional battery charger integrated with renewable energy generation includes a primary side AC/DC rectifier coupled to the electrical grid and a first DC bus, a DC/AC inverter coupled to the first DC bus and a primary winding, a secondary side AC/DC rectifier coupled to a secondary winding and a battery, and a boost converter coupled to a renewable energy generator and the first DC bus. The boost converter includes an active switch controlled by a control algorithm that, when renewable power is available, operates the active switch at a duty cycle that allows power to flow from the renewable energy generator to the first DC bus and on to charge the battery (without passing though the primary side AC/DC rectifier) or on to supply the electrical grid (without passing through the DC/AC inverter and secondary side AC/DC rectifier), and, when not available, disables the active switch.
