Abstract
A system comprises a positive voltage supply node and a negative voltage supply node configured for connection to a load, a power source coupled between the positive voltage supply node and the negative voltage supply node, an energy storage device, a solid-state switch, and a control system. The energy storage device and the solid-state switch are connected in series between the positive voltage supply node and the negative voltage supply node. The control system is configured to control activation and deactivation of the solid-state switch to (i) allow the energy storage device to be discharged and supply power to a load, and to (ii) modulate an amount of charging current that flows through the energy storage device from the power source (or load) to recharge the energy storage device.
