Implementation and Design of Nine Level Inverter With Lesser Number of Switches Using PWM Technique

An H-bridge inverter and a T-Type inverter are used in hybrid MLI. Some prior topologies described used a bigger number of power-switching devices and DC sources, and significant total harmonic distortion, increasing the inverter’s cost and size. For higher-level implementation, the given topology outperforms other similar topologies. The number of driving circuits lowers as the number of switches decreases, reducing the cost, device count and size of the inverter. The level-shifted PWM technique was used to construct and simulate a nine-level inverter in this paper. In addition, the inverter is suitable for nonlinear loads and is compatible with renewable energy grid-connected applications and FACTS. The findings of the simulation are utilised to investigate the performance of multilevel inverters.
