Abstract

Electrostatic transducers represent a very interesting alternative to the traditional inefficient electrodynamic transducers. In order to establish the full potential of these transducers, power amplifiers that fulfill the strict requirements imposed by such loads (high impedance, frequency depended, nonlinear, and high bias voltage for linearization) must be developed. This paper analyzes a power stage suitable for driving an electrostatic transducer under biasing. Measurement results of a plus/minus 400 V prototype amplifier are shown. THD below 1 % is reported.
