Claim Text:
1. A boost type direct current output control circuit device, comprising: an electric control unit (ECU 101 ) connected between direct current input terminals (INPT 101 ) for converting a portion of direct current electrical energy into alternating polarity electric energy; a transformer (TR 101 ) having at least one primary winding (W 1 ) connected to an output of the electric control unit (ECU 101 ) and at least one secondary winding (W 2 ) connected to an input of a bridge rectifier (BR 101 ), the electric control unit (ECU 101 ) converting a portion of the direct current electrical energy from the direct current input terminals (INPT 101 ) into the alternating polarity electric energy and then supplying the alternating polarity electric energy to the at least one primary winding (W 1 ), and the transformer (TR 101 ) outputting the alternating polarity electric energy from the at least one secondary winding (W 2 ) to an input of the bridge rectifier (BR 101 ) for conversion to auxiliary direct current electrical energy and output through auxiliary output terminals (T 3 ); a bypass diode (CR 101 ) parallel connected between the positive and negative terminals of the auxiliary output terminals (T 3 ) of the bridge rectifier (BR 101 ), a current input terminal of the bypass diode (CR 101 ) being connected to a negative terminal of the direct current output of the bridge rectifier (BR 101 ) and a positive one of the direct current input terminals (INPT 101 ), and a current output terminal of the diode (CR 101 ) being connected to a positive terminal of the direct current output of the bridge rectifier (BR 101 ) and to a positive one of direct current output terminals (OUPT 102 ), wherein a negative one of the direct current input terminals (INPT 101 ) is connected to a negative one of the direct current output terminals (OUPT 102 ), and wherein a voltage between the positive and negative output terminals (OUPT 102 ) is a sum of a direct current voltage of the two terminals of the bypass diode (CR 101 ) from the output of the bridge rectifier (BR 101 ) and a voltage between the positive and negative input terminals (INPT 101 ), thereby providing a voltage boost by the voltage formed at the bypass diode (CR 101 ) using only said portion of the direct current electrical energy converted by the electric control unit (ECU 101 ) and output through the at least one secondary winding (W 2 ) of the transformer (TR 101 ) and through the bridge rectifier (BR 101 ).
