Abstract :
This paper introduces the design method of variable frequency power based on IGBT and SPWM inverter technology. The drive signal of IGBT is SPWM wave produced by MCU, and then a undistorted sine signal can be obtained through the low pass filter. LED digital tube displays the voltage value for watching. The sine wave with stably frequency and high precision could be produced by this design.
