IGBT Induction heating power supply commute side control technical characteristics:

• MCS-51 series 89C51 singlechip is the control core, all-digital trigger, intelligent management, perfect protective measures, high capacity of resisting disturbance.
• All digital trigger makes sure the pulse touch off in the uniform interval, greatly reduce the non-characteristic harmonics and grid pollution.
• Double closed circuit PI regulator, to achieve Current/Voltage regulation, ensures constant power output, improve heating effect and uniformity.
• Singlechip phase automatical reorganization technology: The three-phase power supply input line does not need any adjustment, the control circuit will automatically recognize and to complete the rectification trigger function.
• Large plate structure , the control power supply and control circuit is concentrated in a board, to simplify the external line , reducing the point of failure , easy to maintain , improve anti-interference ability .
• Fault protection is of computer self-test forced pull inverter control and regulator seal ring pull inverter control typed, to ensure fast protection for failure.
• Computer self-test function can detect anomalies of the circuit and display on nixietube, to prevent the control circuit from inaccurate protection operates.
• Control circuit has function of soft start, soft stop to prevent over current and over voltage in the process of start / stop.
• Regulator outputs control signals to the A / D converter, interrupt signal finishes reading and starting conversion process. So the maximum adjusting/Delaying time is the A / D converter’s conversion time (about 80μS ) , this ability to respond quickly and rapidity of simulation regulation are very close.
