Abstract
A DC--DC converter includes a transformer having a primary winding and a secondary winding. The secondary winding includes first and second terminals. An input circuit is connected to the primary winding for coupling an input DC voltage to the primary winding. A first output channel is coupled to the first terminal of the secondary winding, and is connected to a first output. The first channel includes a first diode connected in series with a first inductor. A second output channel is coupled to the first terminal of the secondary winding, and is connected to a second output. The second channel includes a second diode connected in series with a second inductor. A first and a second capacitor connect the first and second outputs to the second terminal of the secondary winding. A third diode connects the first output channel to the second terminal of the secondary winding. A fourth diode connects the second output channel to the second terminal of the secondary winding. An amplifier is coupled to one of the outputs. An integrator circuit is connected to the output terminal of the amplifier. A switch having an on and off time is connected to the transformer secondary winding and to the integrator circuit, such that the switch on and off time is controlled by the output of the integrator circuit. A fifth diode is coupled between the transformer secondary winding and the integrator circuit for resetting the integrator circuit.
