  • Charge pump buck converter [articol] 
    Lazăr, Alexandru; Florea, Mihail; Alexa, Dimitrie; Lazăr, Luminița Camelia (Timişoara : Editura Politehnica, 2004)
    The paper proposes a new DC/DC converter topology, based on Buck converter principle. The new converter assures soft turn-on and soft turn-off of the active devices. During of each commutation, the converter pumps a defined ...
  • New control for charge pump buck converter [articol] 
    Lazăr, Alexandru; Florea, Mihail; Alexa, Dimitrie; Lazăr, Luminița Camelia; Lazăr, Georgian Alexandru (Timişoara:Editura Politehnica, 2006)
    The paper proposes a new voltage control methodology for the “Charge Pump Buck Converter”. During each commutation, the converter pumps a defined charge to the load circuit. The original circuit was improved and is able ...
  • The variant of vectorial self - control of the induction machine supplied by a PWM inverter [articol] 
    Alexa, Dimitrie; Pletea, Irinel Valentin; Filote, Constantin; Lazăr, Alexandru; Florea, Mihail (Timişoara : Editura Politehnica, 2008)
    The paper presents a method for the vectorial self - control of an induction motor supplied by a PWM inverter with IGBT transistors. Very good performances are obtained. Considering the dynamic regime for the ...
