Improved performance of a single-phase to three-phase converter using a 4-switch quasi Z-source inverter
This paper proposes an improved space vector pulse width modulation (PWM) control method for a 4- switch single-phase to three-phase converter using a Quasi Z-source (QZs) network that can be utilized in induction motor drive applications. Without using any extra filtering circuits, this method can...

This paper proposes an improved space vector pulse width modulation (PWM) control method for a 4- switch single-phase to three-phase converter using a Quasi Z-source (QZs) network that can be utilized in induction motor drive applications.

In traditional methods, the DC-link voltage without ripple is often achieved at the expense of larger DC-link capacitors that lead to a bulky and heavy DC-link filter with slow response and increase in cost.
