Intelligent recognition of cookware power boards

Abstract

The utility model relates to power mainboard technical field discloses intelligent identification power mainboard of cookware, include: the burning write mouthful, IGBT detection circuit, the bottom sensor detection circuit, CPU circuit, the intelligent identification cookware circuit of different cookware through the pulse number difference of feedback, protection circuit, switching power supply circuit, through the pulse response characteristic of analysis cookware material, automatic matching best heating power, avoid invalid heating, ensure the full safe use of machine, prolong the life of machine, adopt IGBT temperature monitoring, prevent device overheat damage, junction temperature control in safety threshold, and the bottom temperature real -time feedback, avoid food scorched, jumper support forced calibration, with high temperature alarm, improve troubleshooting efficiency, through the design of protection circuit, real -time sampling input voltage, when undervoltage protection, cut off power output, prevent chip abnormal reset, when overvoltage protection, through TVS pipe clamping, avoid breakdown element.
