Conventional Analogy
Inverter Analogy
The driver constantly accelerates hard and slams on the brakes. This results in the wasting
of fuel and excessive noise as a lot of strain is placed on the car's engine.
The driver steadily accelerates and maintains movement consistently by varying the speed
of the car, both speeding up and slowing down to ensure consistent smooth travel from A to B.
This places minimal stress on the engine resulting in reduced noise and fuel consumption,
not to mention less wear and tear.
