This article proposes an optimized discontinuous pulsewidth modulation (O-DPWM) method to reduce leakage current in three-phase three-level inverters under various neutral point
In the future, experimental tests under LVRT events will be performed to further assess the effectiveness of the proposed DPWM in distributing the thermal stresses among the switches and diodes of the 3L
Abstract : This paper presents analytical techniques for the determination of the expressions for the modulation signals used in the carrier-based non-sinusoidal and generalized discontinuous PWM
The proposed technique improves the waveform quality and increases the AC voltage output of the multilevel inverter compared with that from conventional PWM techniques. In addition, it
This paper proposes a three-level power factor adaptive DPWM (PFA-DPWM) strategy developed for T-type inverters. A comprehensive analysis of the harmonic characteristics and
- Firstly, we consider that the inverter is not supplied by the PV solar-Boost converter, and the supply voltage is represented by a DC voltage source with a value of E=125 V.
In this thesis, various DPWM techniques are examined, and they are compared to other conventional PWM methods. The goal of this thesis is to research the advantages and disadvantages of using
