New control algorithm for impedance (Z-source) inverter

A Z-source inverter with a customized modified reference (sine) based pulse width modulation technique is proposed for energy conversion systems e.g. hybrid vehicle. In this system six reference and one carrier signal are used to generate switching pulses. This paper is to demonstrate that the Z-source inverter will boost the AC voltage whenever required, and give minimum output distortion and maximum tracking and interface with the renewable energy system. The control method is analysed with simulation and experimental results. Also the control method is implemented in DSP (TMS320F28335).
