Abstract
  In this paper, two new developed quasi Z-source inverters (QZSI) based on two new diode-cells are proposed. The proposed inverters are called continuous diode assisted quasi Z-source inverter (CDQAZSI) and discontinuous diode assisted quasi Z-source inverter (DDQAZSI). These inverters are thoroughly ...  Read More

Abstract
  This work proposes a new multilevel inverter consisting of basic and submultilevel units. The basic unit is made-up of four isolated dc voltage sources, two bidirectional switches and ten unidirectional switches. To increase the number of the output voltage levels, a cascaded architecture based on series ...  Read More

Abstract
  < p>In power converters, the total harmonic distortion (THD) can be decreased by using two strategies which are filtering and controlling methods. The filtering strategy is indeed costly because of using hardware devices (such as capacitor and inductor). A suitable strategy to control the modern ...  Read More
