Nowadays embedded systems or embedded mechanical brain is very popular. Is used widely such as in power electronics system measurement and control. The system energy conversion system and electric drive. Because it is cheap easy to use, can work freely without the need to connect to a computer. Embedded systems or embedded mechanical brain is processing system for small embedded devices to increase intelligence and ability with those devices through sofwae. At present the technology microcontroller or microcomputer to control work in accordance with the needs very much.
In this project presented the idea of making the control circuit boards are increasingly using dsPIC30F1010. For create the signal P. W. M. In the extended drive is full bridge converter. To compare the signal P. W. M 2 levels and 3 level. Control program works with MPLAB-IDE.
From the results of the trial operation of the power amplifiers the two levels and three levels. When compared it can be seen that there is a difference. Three levels signal spire will be less than the two-level. And the electric current in use of three levels are less than two levels obviously.
