Analysis of the resonance phenomenas in output circuit of a duo-directional power amplifier of D class

The authors consider processes in output circuit of duo-directional amplifiers of the class D, being in operation at low frequency [1. The authors reveal that in consequence of resonance phenomena, conditioned with output capacity of active elements of a duo-directional scheme, it’s possible to reasonably reduce commutative losses in a «silence» mode. The correlations obtained allow to estimate the optimum clock rate in relation to duration of output voltage impulse front.
