This paper proposes Z-source network is connected to multilevel inverter to obtained high voltage gain with reduced THD and voltage stress; here PV cell will act as a DC source. Now a day"s multilevel inverter gives more improvement in AC transmission systems, power quality devices, etc. Normally carrier based PWM techniques are used in conventional inverter, but boost operation is not possible, Z-source network is used to get high voltage gain and reliability. By using different boosting techniques i.e., Simple boost, maximum boost & maximum constant boost gating pulses are generated. The performance of five level diode clamped z-source multilevel inverter has been analyzed. The simulation of five level diode clamped z-source multilevel inverter developed by using MATLAB/SIMULINK

Leprosy has been labelled as a disease with many faces since the time immemorial. This is mainly because of wide range of its clinical presentations depending upon the immune status of the individual. Leprosy is a disease of declining global endemicity, but is still an important healthcare problem in India. Here, we report a case of leprosy with atypical presentation, which was later diagnosed as leprosy when investigated.
