In this research using microcontroller atmega 16 which is the local content. The active power filter built fom SVPWM can be programmed with microcontroller. (1) methods is used to generate active power filter. Have been developed and put into practice. The magnitude of each of the six active vectors corresponding to the maximum possible phase voltage is: Two of these states (SV 0 and SV 7) correspond to short circuit while the other six can be considered to form stationary vectors in the d-q plane as shown in Fig.2. The basic inverter switch states are shown in Figure 1.

The principle of Space Vector PWM is based on the fact that there are only eight possible switch combinations for a three phase inverter. To eliminate or reduce harmonics in the power systems, a number of methods This paper presents an active filter in power inverter control method entitled SVPWM strategy based on microcontroller atmega 16. Design of a signal generator SVPWM applies microcontroller to have some advantages that is easy to be program and inverter circuit to become simple. Besides if generation of signal SVPWM is done digitally will be able to be obtained system work short exchange is more impenetrably to noise. Advantage of technique SVPWM is very economic and practical to be applied operation of three phase AC induction motor. There are some inverter type between it is an inverter power converter with the SVPWM (Space Vector Pulse Width Modulation). Inverter power converter is a voltage converter DC to AC with adjustable voltage and output frequency so that applicable to control three phase AC induction motor. Nowadays, harmonic pollution in electrical powerc systems due to nonlinear loads such as Inverter power converter has become a serious problem. Index Terms - Space Vector PWM, microcontroller, software, varying carrier frequency, amplitude, sinusoidal frequency, analog input. Based on the results of testing and analyzing, it is shown that the SVPWM signals could be implemented with microcontroller Atmega 16 at carrier frequency 490 Hz and THD at sinusoidal frequency of 25Hz, 50Hz, and 100Hz is about 13.85%,Ģ3.89%, and 17.43%. Varying carrier frequency is done by utilizing software with code vision AVR tools, while the amplitude and the sinusoidal frequency are varied by using potentiometers as analog input data. Testing and analyzing system is done at no load condition with varying carrier frequency, amplitude, and sinusoidal frequency. The main feature of the research is the simplicity of the hardware and easy to digitally programmed.
