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.
