Abstract
A multiple output power converter utilizing a circuit on the primary side of a power transformer so as to convert a direct current input into an alternating current output. Said circuit utilizing transistor switching and free wheeling diodes so as to provide continuous current to the primary winding of the power transformer and further utilizing a two winding choke filter in said circuit so as to eliminate the need for choke filtering of the direct current output of a secondary.
Claims13
A circuit connected to the primary winding of a power transformer, said circuit adapted to receive a direct current input, including:
- a connecting means interconnecting said primary winding and direct current input;
- a choke filtering means having two windings interconnected with said connecting means and primary winding;
- and said connecting means capable of causing periodic change in the direction of direct current through the primary winding while periodically connecting separate choke windings thereto to develop an output while allowing the current to be filtered by the choke filtering means.
A circuit connected to the primary winding of a power transformer, said circuit adapted to receive a direct current input, including:
- a connecting means interconnecting said primary winding and direct current input;
- a choke filtering means having two windings interconnected with said connecting means and primary winding, with each choke winding capable of periodically providing a current source to the primary winding during operation of the circuit;
- and said connecting means capable of allowing continuous alternating conduction of current through the primary winding to develop an output while allowing the current to be filtered by the choke filtering means.
