This paper proposed a new type of converter called Single Phase Switched Inductor Z-source Matrix Converter (SLMC). It is an ac-to-ac converter with diode bridge bidirectional switch cell. The limitations of existing matrix converter like voltage regulation and quality output issues are overcome in the proposed SLMC by adding the switched inductance. The simulation is performed for different frequencies. The simulation results are presented to verify unit gain operation and compared with the existing Z-source matrix converter. A prototype was constructed with a voltage of 20Vrms/50Hz. The performance of the proposed converter verified rms with this hardware model. The experimental output voltage amplitude can be varied with the variable frequencies. The output voltage and Total Harmonic Distortion (THD) are observed with 100Hz and 25Hz frequencies for step-up operation. © IDOSI Publications, 2013.
