   Abstract. A reversible d.c. drive system, which employs a four-quadrant chopper with the
   insulated gate bipolar transistors (IGBT), is presented. The chopper circuit employs a
   half-bridge configuration. Excepting the very high power levels, the four-quadrant
   chopper has certain advantages such as: high operational frequency, smooth and linear
   control, high efficiency and fast response.
   Keywords: stepper motor, PWM converter, IGBT gate drive circuit.

   CONVERTOR PWM REVERSIBIL CU TRANZISTOARE BIPOLARE CU GRILĂ IZOLATĂ
                PENTRU MOTOARELE DE CURENT CONTINUU

                                            (Rezumat)

    Se prezintă un convertor reversibil de tip semipunte realizat cu tranzistoare bipolare cu grilă
izolată (IGBT) şi destinat alimentării motoarelor de curent continuu cu excitaţie separată.
Comanda bipolară în tensiune a IGBT-ului se realizează cu un circuit de comandă conceput cu
componente discrete, protecţia la suprasarcină cu traductoare cu efect Hall (modul LEM), iar
semnalele PWM complementare cu “timp mort” sunt generate de un compartiment numeric
realizat cu circuite CMOS.
