The four-switch three-phase (B4) inverter, having a lower number of switches, was first
presented for the possibility of reducing the inverter cost, and it became very attractive as it …

This paper proposes a new dc–ac converter with a reduced number of semiconductor
switches and gate drive and control circuit components. A salient feature of this inverter is its …

High power quality, efficiency, complexity, size, cost effectiveness and switching losses of
the direct current to alternating current (DC–AC) conversion system are crucial aspects in …

The converter consisting of a single‐phase half‐bridge rectifier and four‐switch three‐phase
inverter is a low‐cost power converter with complicated operating constraints. It is difficult to …

This paper proposes performance improvement schemes for sensorless PMSM control drive
using a four-switch three-phase inverter (so-called B4 inverter). In the proposed scheme, the …

A novel 3-phase 4-switch inverter (TPFSI) is described in this study to reduce the inverter's
size, complexity, cost, and losses during the conduction and switching process. This TPFS …

Several inverter faults such as open-phase or loss of the driving signals could terminate the
operation of a PMSM drive. By reconfiguring the two-level three-phase six-switch inverter …

This paper proposes an analytic model for four-switch inverter (FSI)-driven wye (Y) or delta
(Δ)-connected motors with a current ripple reduction algorithm. FSIs employ four switches in …

A four-switch inverter called the B4 inverter is a reconfigured topology of a B6 inverter, one
leg of which is damaged. The four-switch topology provides the overall system with fault …

The main aim of this project is three phase nine level inverter fed induction motor drives for
harmonic reduction in existing system The four-switch threephase (B4) inverter, having a …
