What is Inverter Microwave Oven?

Microwaves have become some of the most essential appliances in our kitchens today. If you can’t stand sitting in the kitchen for one or 2 hours waiting for your chicken to defrost, get a microwave.

Microwaves boast user-friendly features that make them better than traditional cooking methods.


And did you know that microwave manufacturers have introduced new technology to these appliances? Inverter technology makes a microwave more convenient and easy to use.

So what is an inverter microwave? How does it work? What are its pros and cons? We’ve compiled this article to help you figure everything out. So, keep reading.

What is an Inverter Microwave Oven?

An inverter microwave uses an inverter circuit instead of a transformer like a conventional microwave. It delivers a constant stream of power, which leads to faster cooking times and evenly cooked foods.

This microwave takes the existing microwave technology to a whole new level. And just like regular microwaves, inverter models use a magnetron to create microwaves.

Convection microwaves also combine this technology with that of a convection oven for excellent cooking results.

How Do Inverter Microwaves Work?

Inverter microwaves use pulse width modulation to provide continuous heating at reduced power levels for even heating. Food is heated quickly and at a constant power level to avoid loss of flavor.

Rather than turning the magnetron on and off to control temperature, the inverter allows the magnetron to run continuously. It only alters the amount of radiation coming out from the selected setting.

Difference Between an Inverter and a Regular Microwave

What is Inverter Microwave Oven
  • Power Supply

The main difference between an inverter and a regular microwave is how power is delivered. In inverter units, power is supplied through a circuit, while in a solo microwave, it’s supplied through the transformer.

Inverter microwaves supply optimized heat that is constant through the cooking process.

  • Delivery of Heat

Heat is delivered in cycles in a solo microwave to give 100% heat. It works on a switch on/off method.

his isn’t the case in inverter models.

In inverter microwaves, heat is delivered in equal and steady power control for the entire heating process.

  • Flavor of the Food

Inverter microwaves boast regulated power control that helps prevent overheating. Your food will always be rich in flavor.

However, due to the on and off supply of heat in regular microwaves, the chances of food getting overcooked and losing flavor are very high.

  • Energy Efficiency

Inverter microwaves are highly energy efficient. While a regular microwave boasts 56% energy efficiency, an inverter model is 65% efficient.

  • Defrost of frozen food

Although a regular microwave has a defrost function, you’ll still come across complaints of dry edges and cold spots.

With inverter microwaves, heat is distributed evenly in slow cooking. This helps retain the food’s color and texture.

Pros and Cons of Inverter Microwave Ovens


  • More evenly cooked food that is rich in nutrients.
  • Cooks food faster as it doesn’t fluctuate between full power and zero power.
  • More energy-efficient thanks to consistent cooking power.
  • Even defrosting of food at a faster rate.
  • Don’t come with a transformer; thus, lightweight – 3kg lighter than solo microwaves.
  • Don’t alter the food’s flavor.


  • Come at a much higher price than a regular microwave.

How to Clean your Inverter Microwave

Due to the crucial job an inverter microwave does, you must keep it clean at all times. Remember, it’s very easy for foods and liquids to spill over the dish and spill in the microwave.

Always wipe down these spills as soon as they occur. This prevents constant “baking” of spills that can become harder to remove.

Follow these steps to clean your inverter microwave:

Clean with Vinegar/Lemon Solution

  1. Get a microwave-safe cup and fill it with water.
  2. Add slices of lemon to the cup.
  3. Alternatively, fill a cup with water and another with vinegar
  4. Place the cup(s) in the microwave and heat until the oven’s interior is full of steam.
  5. Switch off the microwave and wait for at least 5 minutes before opening the door.
  6. Remove the cup(s) and wipe down the interior with a clean kitchen towel.

Tough Stains

For tough stains, sprinkle baking soda and wait for it to foam. After the foaming subsides, use a clean kitchen towel to wipe away the stains.

Frequently Asked Questions

Q: What does inverter technology in a microwave mean?

Inverter technology in a microwave allows the magnetron to run continuously for fast and even cooking results.
In inverter microwave ovens, a steady and constant stream of power is delivered via an inverter circuit.

Q: What does a microwave inverter do?

A microwave inverter helps supply a constant stream of power for fast and even cooking.

Q: What is inverter microwave cooking?

Inverter microwave cooking is where a microwave uses inverter technology to defrost heat or reheat food at a constant power level.

Q: Are inverter microwaves better?

Inverter microwaves are better than regular microwaves as they cook more evenly and faster.

Q: Are microwaves energy-efficient?

Microwaves are more energy-efficient than stovetops and ovens as they cook in less time.

Q: Can you run a microwave on an inverter?

Yes, you can use a pure sine wave or modified sine wave inverter to run a microwave.

Q: What does half-power mean on a microwave?

Half power in a microwave means that the microwave produces microwaves 50% of the time and zero microwaves for the other 50% of the time.

Q: How do I know the power of my microwave?

To know the wattage of your microwave, check the serial number plate, the inside of the unit’s door, or in the user manual.

Q: Does an inverter microwave brown food?

Inverter microwaves cook from the inside out hence can’t brown food.

Q: What’s the best wattage for a microwave?

A 1,000-wattage microwave cooks quickly and efficiently. It’s, therefore, a great baseline.


An inverter microwave will help you cook meals faster and more evenly without using a lot of energy. If you’re always keen on the flavor and nutrient retention in your food, you’ll love this unit.

The inverter technology helps thaw food without leaving cold spots or destroying the food’s structure.
