| Abstract: | This paper presents a novel design of instant water heater.To resolve the problems in the popular instant water heaters,the feed-forward based on input water temperature,water flow and power supply voltage is added to the PID regulator.Based on the S3F9454 microprocessor,the TRIAC is fired by phase-shift method in order to adjust the heat power.The principles of hardware circuits and the implementation of software are introduced with emphasis in this paper. |
