Abstract
A transformer based isolated bi-directional DC-DC power converter may have signals for controlling power transfer in first and second directions are derived from the same side of the transformer. The converter may include a transformer, a first switching circuit, a second switching circuit, and a controller. In a first mode, the controller controls the first and second switching circuits, and power is transferred from a first side to a second side. In a second mode, the controller controls the first and second switching circuits, and power is transferred from the second side to the first side.
