Abstract

PURPOSE: To obtain an optional output power, by limiting the current and voltage of a power amplifier by means of a serial resistance.
CONSTITUTION: The electric power is supplied to the power supply terminal P1 of the power amplifier 1 formed with the BTL circuit via the power supply circuit 2 comprising the serial resistance R1 and smoothing capacitor C1. Then the current and voltage of the amplifier 1 are limited by the resistance value of the resistance R1. Thus the output power can be limited.
