IH Cooking Heater (Low-End)
详情介绍
Overview
IH cooking heaters with single-burner are getting more and more popular in the market because they are energy-saving and safe as they do not use fire. In recent years such units have become smaller; moreover, their price has become more affordable as their popularity has grown. Low-end cooking heaters are perceived to be attractive alternatives to conventional electric hot plates and portable gas stoves.
The microcontrollers from Renesas Electronics in the M16C/65 Group, RL78 Family and the R8C Family are excellent design choices for use as control microcontrollers in single-burner IH heaters because they have the on-chip PWM (Pulse Width Modulation) timers needed for driving the IH coil drive, and have sufficient performance and functionality to also control the operation of the display panel. Other chips recommended for this type of application include control TRIACs and IGBTs. Using Renesas solutions, it is possible to create designs that achieve improved performance, consume less power, and have lower cost.
