Abstract: A bi-directional DC/DC converter includes at least one module having a module input for providing a bi-directional module input current, and a module output with an output inductor for providing a bi-directional module output current. A transformer has a primary winding wound around a transformer core and connected to the module input, and a secondary winding wound around the core and connected to the module output. A primary set of switches is connected in an H-bridge configuration between the module input and the primary winding. And, a secondary set of switches is connected in an H-bridge configuration between the module output and the secondary winding. A current sensing component senses the module output current. A hysteretic control drives the primary set of switches to control flux. The hysteretic control drives the secondary set of switches to control the module output current as a function of the sensed module output current.

The bus may be a DC bus or an AC bus. The input converter is configured to convert the input DC waveform to a DC or AC bus waveform. The output converter is configured to convert the bus waveform to the output AC waveform at a grid frequency. The active filter is configured to reduce a double-frequency ripple power of the bus waveform by supplying power to and absorbing power from the power bus.

Abstract: An apparatus and method for supplying energy to a load includes an energy recharge unit, an energy storage unit, an energy converter connected to the energy recharge unit, the energy converter being capable of transferring energy at a power level from the energy recharge unit to an output node, the power level being determined by a power transfer controller, and a bi-directional energy converter connected to the energy storage unit and to the output node. The bi-directional energy converter is capable of converting energy of varying voltages from the energy storage unit to energy of varying current levels to supplement the transferred energy with energy from the energy storage unit so as to maintain a constant voltage on the output node. The bi-directional energy converter is capable of converting the transferred energy to provide charging energy to the energy storage unit when the transferred energy exceeds a demand level of the load while maintaining the constant voltage at the output node.
