This paper proposes a new control method for a voltage-source series-resonant inverter (SRI) of the induction heating system. The proposed method of control is based on combining the phase-shift (PS) and pulse-density-modulation (PDM) controls. The main feature of this control method is that the current regulation for pulse density in the range from 0.5 to 1 is provided by only the traditional PDM control and in the range from 0 to 0.5 – with the PS control and constant density equal to 0.5 of the PDM control. Theoretical analysis shows that using the proposed control method can reduce the peak-to-peak current fluctuation and increase the minimum peak current of the SRI, compared with the traditional PDM control. The results of numerical computations are in good agreement with the results of simulations. Experiments were carried out to confirm the practical applicability of the proposed control method for series-resonant inverters for induction heating application.

W artykule zaproponowano nową metodę sterowania falownikiem rezonansowym szeregowym ze źródłem napięcia (SRI) systemu ogrzewania indukcyjnego. Proponowana metoda sterowania opiera się na połączeniu sterowania przesunięciem fazowym (PS) i modulacji gęstości impulsów (PDM). Główną cechą tej metody sterowania jest to, że regulację prądu dla gęstości impulsów w zakresie od 0,5 do 1 zapewnia tylko tradycyjne sterowanie PDM, a zakresie od 0 do 0,5 - ze sterowaniem PS i stałą gęstością. Analiza teoretyczna pokazuje, że zastosowanie proponowanej metody sterowania może zmniejszyć wahania prądu międzyszczytowego i zwiększyć minimalny prąd szczytowy SRI w porównaniu z tradycyjnym sterowaniem PDM.
