Title: Pwm amplifier
Inventor: TSUJISHITA MASAHIRO
IPC: H03K7/08
Filed: 1993-04-14
Abstract: PURPOSE:To reduce the power loss of the PWM amplifier when an amplitude of an input signal is small without increasing distortion. CONSTITUTION:The amplifier is made up of a triangle wave generator 2, a voltage comparator 3 applying PWM modulation to a triangle wave signal with an input signal, a switch drive circuit 4, MOS FETs 5, 6 driven by the switch drive circuit and amplifying power of the PWM signal, a filter 7 extracting a signal whose power is amplified from the PWM wave, and a signal level detector 9 detecting the amplitude of the PWM wave subjected to power amplification. Then the triangular wave generator 2 is controlled so that the oscillating frequency is lower as the modulation of the PWM wave detected through the signal level detector 9 is low (at small signal) thereby reducing the switch loss at a small signal.
