FIELD: electricity.
SUBSTANCE: resonance power amplifier contains an input transformer, n amplifying cascades from n step-down power transformers interconnected by means of n in-series resonance circuits where n=2, 3, …, m, and a feedback device providing unidirectional motion of electric energy from the secondary winding of the last power transformer to the primary winding of the input transformer.
EFFECT: improvement in amplification coefficient of the resonant converter up to 2-10 and stabilisation of amplification coefficient at load and frequency change.
