FIELD: electricity.
SUBSTANCE: invention relates to electric engineering and can be used as power supply source with rectifier/inverter with induction heating or melting device. Device includes trimming capacitor connected between rectifier output and inverter input, which forms resonance circuit with inducer at inverter operating frequency. Besides, inducer can be formed of active inducer connected to inverter output and passive inducer switched in parallel with resonant trimming capacitor.
EFFECT: provision of resonant circuit with inducer.
