What is the Difference Between Inverter Microwave & Regular Microwave?

It is none other than the microwave, which always stands first to cook our favourite food within no time. Isn’t it?

The user-friendly features in it keep the oven a step ahead of the traditional cooking method. The manufactures of the microwave are also getting advanced by introducing new technology.

In that case, microwaves are now having two types in the market.


  • Regular Microwave
  • Inverter Microwave

But what makes them different from each other. If Are you in search of the differences between the types of microwave ovens based on their functioning?

Then, sit back and relax. You have reached the right platform.

So, the question you might be searching for is “What is the Difference Between Inverter Microwave & Regular Microwave?” The basic difference between them is the power supply conversion. The inverter microwave gets power supply through the circuit, whereas the regular microwave gets power supply through the transformer. The main advantage of an inverter oven is it supplies optimized heat and is constant throughout cooking.

There are some other differences to compare to get a clear understanding of microwave oven with inverter and without an inverter. If you are interested in knowing further details.. scroll down…

Difference Between Inverter Microwave & Regular Microwave

Both microwave ovens heating process involves the magnetron to produce the microwaves. And these microwaves make the water molecules vibrate and result in the production of heat in the food.

But the differences come in how the oven maintains the food during cooking by the power supply.

Before getting started, let us know how a normal microwave gets a power supply…

Difference Between Inverter Microwave & Regular Microwave

Power Supply to Normal Microwave Oven:

The power supply to the microwave oven is done through the transformer, which is present at the power inlet of the oven. The main function of a transformer is to step up or step down the electricity to higher voltages. In this, the transformer makes the AC increase/ decrease according to the food heating cycle. It is the basic model of the microwave oven.

Power Supply to Inverter Microwave oven:

The power supply to this microwave oven is done through an inverter circuit instead of a transformer used in a normal microwave oven. This inverter will supply the same voltage throughout cooking without increasing/decreasing that produced in a normal oven.

The power will be supplied to the magnetron from the transformer and inverter, which helps produce the microwaves. These microwaves penetrate the food and make the water molecules vibrate.

Thus, heat is produced in the food.

Delivery of Heat:

As said earlier, the difference comes in the power supply, which indirectly means heat delivery.

In the normal microwave oven, the heat delivery is in cycles to give 100% heat. So, it works on the switch on and off method with heavy and low efficient power supply.

But, whereas in the inverter microwave, the heat is supplied in equal and steady with a linear power control throughout the heating process.


When it comes to energy efficiency, a normal microwave oven has 56% of energy efficiency while the inverter microwave oven has 65% energy efficiency.

The flavour of the food:

Due to the on/off power supply, the heat will overheat the food, i.e., damage the food cells, resulting in burned food edges and flavour loss.

While in the case of an inverter microwave oven, the regulated power control helps prevent the damage-causing from the food cells and results in flavour-rich food.

Nutrients in Food:

There is a drawback in the microwave oven: the food in a microwave oven will lose its nutrients and make it as the dead nutrients less food.

The drawback of the normal microwave oven can be overcome with an inverter microwave oven. According to the Cornell University’s Dept. of Nutritional Sciences Study, the food cooked in the inverter microwave oven will enhance the nutrients in food after cooking in it.

Defrost of frozen food:

Though the normal microwave oven has the defrost method, there are some complaints like cold spots, dry edges…etc. Has been registered.

With the liner power supply, the heat is evenly distributed in slow cooking and a moist environment. It makes the food retain its colour and texture after cooking also.

Must Watch Video of Difference between Normal and Inverter Microwaves

This video will let you know the differences between them with some clear visuals.



Finally, if you hurry in cooking during the festival time and want to maintain the food’s heat, this inverter microwave oven is the best choice.  As technology increases, the drawbacks of the present product will be overcome in the next updated product. So, we need to be aware of the technical stuff.

Frequently Asked Questions:

Can you put metal in an inverter microwave? No, you cannot put metal in an inverter microwave oven because any metal will reflect the microwaves in the oven and result in sparking inside the oven and even cause damage.

What is the best wattage for a microwave? The best wattage reading for a microwave to cook food efficiently and evenly is 1000 watts. This powerless will make the process of cooking slowly with low heat and gives unevenly cooked food.

Which oven is best for cakes? Convection ovens are the best for baking purposes. It helps to bake cakes, pizzas, muffins…etc., with the hot air circulation inside the cooking chamber. You can also choose a microwave oven with a convection option which gives you the best way to bake and cook food.

What is a solo-type microwave oven? It is also a microwave oven with a basic heating process like reheating, defrosting, cooking. It is not able to grill or bake the food.

Are microwaves radioactive? No, the microwaves used in the microwave oven are not radioactive because the microwaves make the food hot by vibrating the water molecules in the food and producing frictions. The friction is nothing but the heat produced by the water molecules. But it does not make the food a radioactive element.
