  • E-learning practical teaching of uncontrolled rectifiers [articol] 
    Lascu, Dan Florentin; Lascu, Mihaela Ruxandra; Băbăiţă, Mircea-Ilie; Popescu, Viorel; Negoiţescu, Dan; Popovici, Adrian (Timişoara:Editura Politehnica, 2008)
    The paper describes blended learning approach to teaching uncontrolled rectifiers. It is based on “Learning by Doing” paradigm supported by several learning tools: electronic course materials, interactive simulation, ...
  • Novel nonlinear digital controller for a buck converter with dead beat characteristic [articol] 
    Biru, Getachew; Keller, Günter; Lascu, Dan Florentin (Timişoara : Editura Politehnica, 2008)
    The static and dynamic characteristics of buck converters are well known for a long time. An easy approximation results in a first order transfer function in discontinuous conduction mode (DCM). Based on the description ...
  • A quadratic boost converter with PFC applications [articol] 
    Lascu, Dan Florentin; Negoiţescu, Dan; Lascu, Mihaela Ruxandra; Popescu, Viorel (Timişoara:Editura Politehnica, 2006)
    A novel quadratic boost converter capable of delivering a high output voltage is introduced. Dc-dc operation in continuous conduction mode (CCM) and discontinuous inductor current mode (DICM) are analyzed. A simple and ...
  • State-space control structures for buck converters with/without input filter [articol] 
    Keller, Günter; Lascu, Dan Florentin (Timişoara : Editura Politehnica, 2004)
    Power supplies normally provide a constant output voltage. In most of the applications a DC/DC-converter is controlled by a voltage mode or a current mode controller. Often these controller types are combined with feed ...
  • Transferul controlat al energiei prin convertoare PWM şi rezonanţe 
    Lascu, Dan Florentin (Universitatea „Politehnica" din Timişoara, Facultatea de Electronică şi Telecomunicaţii, 1998)
