Abstract

Il circuito comprende due terminali di uscita (OUT 1, OUT 2) per il collegamento ai terminali ad un carico (L);una prima ed una seconda coppia di interruttori elettronici di potenza (Q1, Q4; Q2, Q3), collegati fra i terminali di uscita (OUT 1, OUT 2) e i due poli di una sorgente di tensione continua di alimentazione (Vs) in modo da formare con il carico (L) una struttura ad H; e un circuito di pilotaggio (C1, C2) atto a rendere selettivamente conduttivi gli interruttori elettronici di potenza della prima (Q1, Q4) e rispettivamente della seconda coppia (Q2, Q3) per determinare il passaggio di corrente nel carico (L) in un verso e rispettivamente nel verso opposto, ed atto ad impedire la conduzione simultanea negli interruttori elettronici (Q1, Q3; Q2, Q4) connessi fra un medesimo terminale di uscita (OUT 1; OUT 2) e i due poli della sorgente di tensione (Vs).(Fig. 2).
