A power supply having an specified hold-up time to take a input voltage and convert it to an output voltage, comprising: a first power stage to receive the input voltage; a second power stage to generate the output voltage and an output current; an intermediate charge storage device coupled between the first and second power conversion stages providing an intermediate output voltage in response to the input voltage; and a controller that controls the intermediate output voltage according to a voltage function that is associated with the hold-up time.

A power supply includes power modules. Each of the power modules includes an input stage and an output stage. The input stage generates an intermediate voltage, and the output stage outputs a DC supply voltage according to the intermediate voltage. The input stages are controlled with at least one first common control signal having a common duty cycle, and the output stages are controlled with at least one second common control signal having a common duty cycle.

H02M 3/335

A flux-balancing method for an isolated bidirectional converter uses a flux-balancing control loop and a current-balancing control loop to control the DC components in the primary and secondary currents. The flux-balancing control loop keeps the average magnetizing current substantially zero and the current-balancing control loop keeps the average primary current or the average secondary current substantially zero. The flux-balancing loop adjusts the duty ratio of a set of switches in a corresponding bridge. The adjusted duty ratio is designed to substantially eliminate the DC component in the magnetizing current. The current-balancing loop keeps the average primary current and the average secondary current substantially zero, and adjusts the duty ratio of the switches in a corresponding bridge to eliminate the corresponding DC component.

A power converter topology is adapted for efficiency according to input voltage, output voltage or output current conditions. Topology adaptation is achieved by control responsive to the input and output operating conditions, or to one or more external control signals. Transition between any two topologies is implemented by pulse width modulation in the two switches in one of two bridge legs of a full bridge converter. When transitioning from full-bridge to half-bridge topology, the duty ratio of one switch in one leg of the full bridge is increased, while simultaneously the duty ratio of the other switch in the same leg is reduced until one switch is continuously on, while the other switch is continuously off. The transition from the half-bridge to the full-bridge topology is accomplished by modulating the same switches such that, at the end of the transition, both switches operate with substantially the same duty cycle.
