A novel AC heating system for man-made diamond was introduced and the model of the heating system was established. Three types of AC heating system,including constant power,constant average voltage and constant root mean square (RMS) voltage AC heating system were analyzed. Finally,constant power AC heating system was adopted. The principle and characteristics of the pulse control and detection part were ana-lyzed in depth. A bias analog PI controller was used as the control core;meanwhile,the principle and steps for controller parameter setting were discussed. Simulation and experiment results show that the suggested heat-ing system has characteristics of good real-time capability, high control precision, favorable dynamic and static behaviors as well as easy realization. It can well meet the technical requirements of diamond synthesizing.
