Abstract

A bidirectional DC DC converter that transfers power among an energy source (for example, a solar PV array), an energy storage system, and an energy usage system (for example, a DC AC inverter). The converter controls the charge and discharge times of the energy storage system so that power harvested during daylight can be metered to the DC AC inverter at predetermined times. During charge times, the converter utilizes synchronous rectification when down-converting higher voltages to lower voltages and during discharge times the converter utilizes variable overlapping of switch drive signals to provide a continuous range of voltage levels of transferred power from the energy storage system to the DC AC inverter.
