Abstract

A MULTI-OUTPUT SWITCHING POWER UNIT WHICH CAN SUBSTANTIALLY PREVENT AN OUTPUT POWER SUPPLY OF AN AUXILIARY OUTPUT POWER CIRCUIT FROM DROPPING SIGNIFICANTLY WHEN A LOAD A IS LIGHT AND WHICH HAS A REDUCED LOSSIN THE OUTPUT PATH. A VOLTAGE UP CAPACITOR 20, A FIRST DIODE 21, A SECOND DIODE 22 AND A SERIES REGULATOR 13 ARE PROVIDED IN THE AUXILIARY OUTPUT POWER CIRCUIT 9 INCLUDING A CHOKE RECTIFIER CIRCUIT 4. WHEN THE LOAD A IS LIGHT AND AN OUTPUT VOLTAGE V2 OF THE AUXILIARY OUTPUT POWER CIRCUIT 9 DROPS TO BELOW THE PREDETERMINED VOLTAGE OF THE SERIES REGULATOR, THE SERIES REGULATOR 13 IS PUT INTO A CONDUCTIVELY CONNECTED STATE. THEN, AN OUTPUT OF AN OUTPUT AUXILIARY COIL 15 FLOWS IN THE AUXILIARY OUTPUT POWER CIRCUIT 9 TO AN AUXILIARY CHOKING COIL L2 AS WELL AS ALONG A ROUTE PASSING THROUGH THE VOLTAGE UP CAPACITOR 20, THE SECOND DIODE 22 AND THE SERIES REGULATOR 13, CHARGES THE VOLTAGE UP CAPACITOR 20, STEPS UP A VOLTAGE AT THE INPUT END SIDE OF THE AUXILIARY CHOKING COIL L2 AND SUPPLIES SUBSTANTIALLY THE SAME VOLTAGE TO A LOAD B. AS THE VOLTAGE BEFORE THE DROP IN THE OUTPUT VOLTAGE V2 OCCURRED.FIG 1
