The use of inverters can increase or decrease the power or torque of the motor by adjusting the amplitude of the signal.

It plays a significant role in capturing energy from regenerative braking and feeding it back to the battery. The key component is that it has a direct impact on on-road performance, driving range, and reliability of the vehicle also as a consequence of their weight and size.

The output voltage waveform of ideal inverters should be sinusoidal. However, the waveform of practical inverters is non-sinusoidal and contains certain harmonics.

There are five main types of converter in this non-isolated group, usually called the buck, boost, buck-boost, Cuk and charge-pump converters. The buck converter is used for voltage step-down, while the boost converter is used for voltage step-up

Some key applications where DC/DC converters are employed extensively include renewable energy integration, medical devices, vehicles, smart lighting, and other small-scale electronic appliances.
