Why does my Philips Induction Cooktop not maintain the temperature when cooking roti?

Preparing roti is different than other recipes since here vessel temperature should be maintained very high at all times and generally larger base vessel is used.

In normal usage, after preparing a few roti, the oversize vessel transfers the temperature to the cooktop surface and the thermal protection circuit discontinue the supply to let cool down the appliance.

As a result, there will be a drop in the temperature of your induction cooktop. This is normal and it happens to make the product safer and a longer life.
