Abstract
PURPOSE: To increase the efficiency by adding another constant voltage power unit to the serial control type constant voltage power unit the power efficiency is not so good.
CONSTITUTION: The collector current of amplifying transistor 2 included in constant voltage power unit 11 is connected to constant voltage power unit 12 for low power use. At unit 11, the collector of transistor 2 is led outside to obtain two types of output voltage at output terminals 10 and 15 each. In such way, the collector current of transistor 2 which is not used yet, i.e. the astable collector voltage is stabilized through the constant voltage circuit to be utilized for part of the power source for the communication apparatus. As a result, the overall efficiency can be increased for the power unit.
