Research on stage lighting control technology based on sine wave

With the rapid development of stage equipment in recent years, the traditional SCR Dimming control technology is difficult to complete the performance requirements of stage lighting. In this paper, we proposed and researched the stage lighting dimming control technology based on sine wave, which used Atmega16 microcontroller, IXDP610 chip and IGBT as the main hardware. We could receive the DMX512 data sent from lighting console, and control IXDP610 chip to generate PWM signal with adjustable duty cycle and dead time by the microcontroller. This PWM signal can control the IGBT through driving circuit to achieve the purpose of dimming. According to the simulation and experimental results, this technology has a good dimming performance and it can effectively avoid the generation of harmonics. The research has theoretical significance and practical value to the development of stage lighting dimming control technology.
