To describe the operating principle and control, this paper focuses on an example: a Z-source inverter for dc-ac power conversion needed in fuel cell applications.

To be able to provide 220VAC electrical power, solar power generation system needs to be issued by the exchange of DC can be converted into electrical energy, so need to use the DC-AC inverter.

The chip TL1451A is a chip of switch about controlling DC-AC inverter, the features and functions of chip TL1451A is introduced, is applied to the inverter of back light in LCD.
