Abstract

Przedmiotem wynalazku jest układ pośredniego przemiennika częstotliwości z quasi - rezonansowym układem pośredniczącym, w którym quasi - rezonansowy obwód pośredniczący (PQR) składa się z włączonych pomiędzy zaciski wyjściowe prostownika (P) szeregowo połączonych dwóch kondensatorów (C1, C2), do których punktu wspólnego przyłączony jest biegun cewki rezonansowej (LR), której drugi biegun jest włączony do punktu wspólnego szeregowo połączonego drugiego tranzystora (T2) z trzecim tranzystorem (T3), tworzących gałąź włączoną pomiędzy zaciski wejściowe falownika (F). Przeciwrównolegle do drugiego tranzystora (T2) przyłączona jest druga dioda (D2), zaś do trzeciego tranzystora (T3) trzecia dioda (D3), przy czym pomiędzy dodatnim biegunem wyjściowym prostownika (P) a dodatnim biegunem wejściowym falownika (F) włączony jest pierwszy tranzystor (T1), do którego przeciwrównolegle włączona jest pierwsza dioda (D1). Pomiędzy ujemne bieguny wyjściowe prostownika (P) i wejściowe falownika (F) włączony jest czwarty tranzystor (T4) i przeciwrównolegle do czwartego tranzystora (T4) włączona jest czwarta dioda (D4), zaś pomiędzy bieguny wejściowe falownika (F) włączony jest kondensator rezonansowy (CR).The subject of the invention is an intermediate frequency converter system with a quasi-resonant intermediate circuit, in which the quasi-resonant intermediate circuit (PQR) consists of two capacitors (C1, C2) connected in series between the output terminals of the rectifier (C1), to which a common point connected is the pole of the resonant coil (LR), whose second pole is connected to the common point of a series-connected second transistor (T2) with the third transistor (T3), forming a branch connected between the input terminals of the inverter (F). Opposite to the second transistor (T2), the second diode (D2) is connected, and to the third transistor (T3) the third diode (D3), with the first transistor connected between the positive output pole of the rectifier (P) and the positive input pole of the inverter (F) (T1), to which the first diode (D1) is connected in parallel. The fourth transistor (T4) is connected between the negative output poles of the rectifier (P) and the input inverter (F) and the fourth diode (D4) is connected in parallel to the fourth transistor (T4), and the resonant capacitor (F) is connected between the input poles of the inverter (F). CR).
