| Abstract: | With the application of multilevel inverters in high power occasions,various multilevel inverter topologies have been proposed.A hybrid cascade asymmetric multilevel inverter scheme is validated,in which the traditional H-bridge inverter is improved to output more level numbers using the same devices or output the same level number using less devices.The asymmetric inverter consists of two asymmetric four multilevel inverters and outputs seven levels at least.This scheme can be used in independent power supply system,such as electric vehicle motor drive and shipborne propulsion system.Hybrid cascaded asymmetric multilevel inverter with separated DC supplies is analyzed.The Phase Opposition Disposition PWM(PODPWM)modulation method is employed. FPGA logic device is chosen to produce PWM signal.Finally,the validity of the design was confirmed by debugging the built hardware circuit. |
