Comparison of seven levels symmetric h-bridge multilevel inverter and seven levels cascaded h-bridge multilevel inverter

An inverter is a power converter that transforms DC power to AC power using controlled power semiconductor switches. The inverter is categorized into many types based on output, source, type of load etc. This proposal focused on voltage source inverters. Voltage Source Inverter is further classified...
