Abstract
A multi-output, multi-directional power converter has an input bi-directional switch and at least a first output bi-directional switch, a coupled inductor having an input winding and at least one output winding. The coupled inductor input winding is connected in series with the input voltage source and an input bi-directional switch. Each coupled inductor output winding is connected in series with a corresponding output voltage source such as a capacitor and its respective output bi-directional switch. A clock circuit provides a first and second control signal. Each control signal has a first and second state. The second control signal has a state that is the complement of the first control signal. The first control signal is connected to the input bi-directional switch control terminal and the second control signal is connected to each respective output bi-directional switch control terminal. The input bi-directional switch is driven into a conductive state in response to the first control signal being in a first state and into a non-conductive state in response to the second control signal being in a second state. Each respective output bi-directional switch conduction channel is driven into a conductive state in response to the second control signal being in a first state and into a non-conductive state in response to the second control signal being in a second state. In an alternative embodiment, a resonant transition control means senses the coupled inductor input and output winding currents and the output voltage and adjusts the clock frequency to provide operation in a resonant transition mode.
