Sirous Toofan; Babak Fathipour; Ebrahim Babaei

Volume 7, Issue 4 , December 2024, , Pages 281-290

https://doi.org/10.22111/ieco.2024.48295.1548

Abstract
  — In this paper, a single switch transformer-less DC-DC converter with continuous input current for photovoltaic applications is proposed. The suggested configuration utilizes a CL1C2D2 structure to achieve a high voltage gain and alleviate voltage pressure on the semiconductor components. This ...  Read More

Roya Naderi; Ebrahim Babaei

Volume 6, Issue 2 , June 2023, , Pages 123-131

https://doi.org/10.22111/ieco.2023.43888.1453

Abstract
  In this paper, a new basic unit is proposed for multilevel inverters. Then, a series connection of the proposed basic unit is used to recommend a new topology for multilevel inverters. To determine the magnitude of dc voltage sources, a new algorithm is presented. For the proposed algorithm, different ...  Read More

Sara Laali; Ebrahim Babaei

Volume 5, Issue 1 , March 2022, , Pages 51-62

https://doi.org/10.22111/ieco.2022.36797.1328

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

Optimization of a New Extended Cascaded Multilevel Inverter Topology to Reduce DC Voltage Sources and Power Electronic Components

Roya Naderi; Ebrahim Babaei; Mehran Sabahi; Ali Daghigh

Volume 4, Issue 4 , November 2021, , Pages 465-474

https://doi.org/10.22111/ieco.2021.36599.1322

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

PWM Control Methods Based on Mathematical Equations for Z-Source Inverters

Taher Ahmadzadeh; Ebrahim Babaei; Mehran Sabahi; Taher Abedinzadeh

Volume 4, Issue 2 , April 2021, , Pages 167-179

https://doi.org/10.22111/ieco.2020.34508.1279

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
