A nine level hybrid inverter is introduced here. It is a combination of diode clamped and H bridge topology. The power switches are gated using APOD SPWM technique at a switching frequency of 10 kHz. The number of levels can be increased by the addition of capacitors, switches and diodes. The capacitor voltage is balanced using a Resonant Switched Capacitor Converter (RSCC) circuit. The performance analysis is carried by MATLAB 2017/Simulink environment. With an input voltage of 155V DC and an

The hardware implementation of the control strategy is done by using PIC16F877A microcontroller and Arduino MEGA 2560 microcontroller. MOSFET IRF540 is used as switching device. The prototype of the hardware is implemented for an input voltage of 36V and an output of 35.6 V, 50 Hz is obtained.
