Title: Electric power controller
Inventor: IIZUKA SHOGO
IPC: G05F1/10
Filed: 1987-09-11
Abstract: PURPOSE:To improve the temperature characteristics and to reduce the variance of output power between sets by storing the actual output voltage of a power amplifier as the reference value in response to the ambient temperature and the set output power value. CONSTITUTION:The measured value data obtained by converting the actual output voltage of an output voltage detecting circuit 2 for various set output power values decided by a power amplifier 1 working at various temperature levels is stored in a memory 6 as the standard data. Then the output voltage is read out based on the set output voltage and the present ambient temperature. The power supply voltage is controlled to the amplifier 1 so that said output voltage is approximately equal to the output voltage of the amplifier 1. Thus the output power of the amplifier 1 is never changed by the ambient temperatures and furthermore the variance of output power due to the ambient temperatures can be avoided between sets.
