How does an inverter work in a microwave oven?

An inverter in a microwave oven regulates the power supplied to the magnetron, which generates microwaves. Unlike traditional microwave ovens that cycle the magnetron on and off to control cooking power, an inverter provides a continuous, steady stream of microwave energy at varying power levels. This allows for more even cooking and better defrosting by maintaining a consistent temperature throughout the food. As a result, food is less likely to overcook or develop hot spots.
