What is DC-DC converter?

DC-DC converter is a category of power converters that convert DC power from one voltage level to another by temporarily storing input energy and then releasing that energy to outputs at different voltages.


How does a DC-DC converter work?

Inside each electric car, there is a battery that produces a certain voltage. Since this voltage may not be suitable for the various devices being driven, we need to install another device in the signal path. This device is called a DC-DC converter, and without it, modern electric cars would not be possible.


The battery of an electric car usually produces a few hundred volts of direct current. However, the voltage requirements of the electrical components within the vehicle vary, and most components operate at much lower voltages. This includes the radio, dashboard readings, air conditioning, and a built-in computer and monitor.


In an electric vehicle using a DC motor, the actual voltage used to run the motor may be three times the voltage provided by the battery. With the help of the right converter, we can bridge this gap without having to use a bigger, heavier battery.


DC-DC converters constitute a complete subcategory of electrical engineering. There are many different ways to do this, all of which are based on the principles of Ohm's Law.


A simplified buck converter might generate a series of on-off pulses and then use a combination of inductors and capacitors to smooth it into a consistent DC signal whose current is constant and whose voltage is determined by the duty cycle (that is, the duration of the "on" state relative to the "off" state).
