After the stove-top pressure cookers came the electric pressure cookers in 1991,<ref name="instantpot.com">{{cite web |title=Three Generations of Electric Pressure Cookers |url=http://instantpot.com/technology/three-generations-of-electric-pressure-cookers/ |access-date=13 November 2018 |website=Instant Pot |archive-date=14 November 2017 |archive-url=https://web.archive.org/web/20171114135416/http://instantpot.com/technology/three-generations-of-electric-pressure-cookers/ |url-status=dead }}</ref> called the "third generation" pressure cookers.

These include an electric heat source that is automatically regulated to maintain the operating temperature and pressure. They also include a spring-loaded valve (as described above) and are typically non venting during cooking.

An electric pressure cooker integrates a timer. Depending on cooking control capability, there are three generations of electric pressure cookers:<ref name="instantpot.com"/>

* First-generation electric, with mechanical timer. There is no delayed cooking capability.
* Second-generation electric, with digital controller. Delayed cooking becomes possible and the controller shows a countdown timer when working pressure is reached.
* Third-generation electric, with smart programming, which includes pre-set cooking times and settings based on heating intensity, temperature, pressure and duration.

Some pressure cookers are multifunctional ([[multicooker]]s): pressure cooker, [[saute]]/[[browning (partial cooking)|browning]], [[slow cooker]], [[rice cooker]], [[egg]] cooker, [[Yogurt#Production|yogurt maker]], [[food steamer|steamer]], [[sous vide]], [[Home canning|canner]], and [[stockpot]] warmer that can also be used to keep cooked food warm.{{citation needed|date=September 2019}} Since 2018, with the release of the [[Ninja (brand)|Ninja]] Foodi pressure cooker, which was the first pressure cooker that could also [[air fryer|air fry]], several other pressure cooker manufacturers, including [[Instant Pot]], have come out with their own pressure cookers that can air fry, which are now known as ''air fryer pressure cookers''. Air fryer pressure cookers generally have two separate lids, one for pressure cooking, and one for air frying.<ref name="Better?">[https://www.digitaltrends.com/home/instant-pot-duo-crisp-vs-ninja-foodi/ Instant Pot Duo Crisp vs Ninja Foodi: Which is Better?]</ref>
