Microwave oven solution based on Renesas R8C series MCU

Author:joy Release time:2017-04-13 Source: Font: Big Middle Small View count:570

Program Description:

This solution adopts Renesas R8C series single-chip microcomputer as the core, R8C family, 3803H series and 3850 series with built-in high-performance CPU. It integrates PWM for IGBT control and rich AD converter for various sensor inputs. Microwave ovens have developed rapidly as cooking appliances. Not only heating food, but also having a variety of cooking functions such as "cooking, frying, frying, steaming, fermenting". In addition, as a healthy home appliance, it is also possible to make healthy dishes that control salt and oil. For this reason, it is becoming more and more important to accurately control the output using data obtained from temperature sensors, infrared sensors, weight sensors, and the like. From the structural point of view, the main output of the microwave oven uses a magnetron, and the IGBT of the high harmonic switch delivers a high voltage to the magnetron.
