Abstract

PURPOSE:To simplify the circuit composition by a method wherein a plurality of source transformers are provided and the time-sharing observation of the voltage and the current to each load is performed. CONSTITUTION:Analogue switches SW1 and SW2 are changed over by a pulse wave supplied by a control circuit CONT. The source is supplied to a load Z1 by a transistor Tr1. The out put voltage V1 is controled corresponding to the load fluctuation by the signal supplied to the control circuit CONT via the analogue switches SW1 and SW2. The circuit is composed in such a manner that the output is supplied to the transistor Tr1 while the analogue switches SW1 and SW2 are selecting the input from the load Z1 and the output is supplied to the transistor Tr2 while the analogue switches SW1 and SW2 are selecting the input from the load Z2.
