This paper present Cascaded Hybrid Multilevel Inverter (CHMLI) is an attractive topology for high voltage DC-AC conversion. This paper focuses on a single-phase five-level inverter with eliminating harmonics. The inverter consists of a two full bridge inverter. The inverter produces output voltage in five levels: 0, +0.5Vdc, +Vdc, -0.5Vdc and –Vdc.. This paper present sequential switching hybrid-modulation strategies for cascaded multilevel inverter and comparison of two hybrid pulse width modulation techniques. the main characteristics of these modulation are the reduction of switching losses with good harmonics performance, balance power loss dissipate among the device with in a cell .the feasibility of these hybrid modulation are verified matlab/simulink software and simulation result are presented. |
