Resonant Phenomena in Output Circuit of Powerful Two-StepDclass Amplifier
Abstract
This paper considers procedures in output circuit of powerful two-step «D» class amplifiers operating at low clock frequencies [1]. It is shown that because of resonant phenomena due to output capacity of two-step active elements, essential decrease of commutative loss in no no-signal condition is possible. Correlation received allows to determine optimal clock frequency dependent on pulse leading-edge time of output voltage.
