In this article, a novel structure for four-switch three-phase inverter with the ability of creating null vector is proposed. This utilizes symmetrical quasi-Z-source network and generates zero output voltage during shoot-through state, which similar to in conventional six-switch inverter. used remaining time each switching period. means that proposed has several advantages over inverter, two a...

Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...

This article proposes a topology for construction of multilevel inverter consisting of H-bridge and level switch. In accordance with the proposed topology Н-bridge inverts voltage and a switch enables to get any number of voltage levels. At that, in comparison with analogues, the above mentioned topology allows saving on expensive power keys. Moreover, a special technique has been developed to ...

The class Φ2 inverter is a new switched mode type of resonant inverter. This inverter is applicable for very high frequency application. In this paper, it proposes class Φ2 inverter reduced the voltage stress, and improve the dynamic response. The class E resonant inverter is not suitable for high frequency application, because it produce high voltage stress across the switch. The suitable ball...

Multilevel inverter (MLI) has emerged as a key player in medium and high voltage application due to its tremendous popularity in reduced voltage stress across the power switches and low total harmonic distortion in output waveform. MLI requires large amount of power switches to perform conversion as compared to conventional converter. In MLI, as the number of levels increase number of switches ...
