This paper presents a new control topology that is dedicated to switching power amplifier systems-Multivariable Enhanced Cascade Control (MECC). MECC provides powerful and flexible control over all essential system parameters as distortion, noise, output impedance, frequency response, etc., by simple means, using standard active and passive components. A 400-W 4-- MECC based power amplifier module is shown to implement state-of-the-art performance. Exceptional linearity with below -100 dB (0.001%) pure THD at typical output powers is combined with >120 dBA dynamic range and 93% power stage efficiency.
