2 HARDWARE IMPLEMENTATION

 

 

In Figure 2-1, SMPS stands for Switch Mode Power Supply. It provides +18V DC and +5V DC to the system. Three out of four comparators are used in this solution: one for synchronization circuit and other two for surge protection and IGBT over-voltage protection.

Table 2-1 shows the pin assignment while using S3F84B8 in IH cooker system.
