Abstract: A power converter includes an input circuit that receives DC input power and creates high frequency pulses. A transformer transforms the high frequency pulses into at least two sets of transformed pulses having alternating and opposite polarity. An output circuit connected to the transformer includes a plurality of switches for blocking undesired pulses. A controller controls the switches so that they are on except when blocking undesired pulses, so that a continuous current path is provided through the output circuit.

Abstract: An electrical power converter receives input power of one type or level at input terminals and supplies output power of another type or level at output terminals. The power converter includes a high frequency transformer, an input circuit connected between the input terminals and the primary of the transformer, and an output circuit connected between the secondary of the transformer and the output terminals, a controller for controlling pulse width of current pulses produced by the input circuit, and a current limiting circuit. The current limiting circuit allows very high surge currents immediately upon demand without waiting for a voltage drop feedback circuit, then dynamically reduces the current limit over time based on the averaged current in the input circuit.

Abstract: A power converter for converting DC to AC power or DC to DC power includes an input circuit, a transformer, an output circuit, and a controller. The input circuit receives DC input power and creates high frequency pulses. The transformer transforms the high frequency pulses into at least two sets of transformed pulses, the sets of transformed pulses having alternating and opposite polarity. The transformer includes a primary winding and a secondary winding, where the primary winding is connected to the input circuit. The output circuit includes a plurality of switches for providing a full wave rectified or DC output, where the output circuit is connected to the secondary winding. The controller controls the switches to provide a continuous current path through the output circuit thus minimizing voltage spikes and ripple, and greatly reducing the cost and complexity of the output circuit usually required to handle these spikes and ripple.
