Technical Electrodynamics| Резюме: | Using a pulse density modulation (PDM) for regulating and stabilization of a transistor converter’s load current for induction heating equipment, with the number of pulses during a modulation period divisible to the half-period of an inverter’s output voltage is considered in this paper. A mathematical model of the resonant voltage inverter under PDM and analytical equations for maximum and minimum current amplitudes and their difference determining the swing of the ripple current’s amplitude were obtained. It is made clear that PDM with the number of pulses during a modulation period which is divisible to the half-period of the inverter output voltage allows, on average, to reduce the swing of the ripple current’s amplitude and enlarge the regulation range of the load current.
