Why do I need DC-DC Converter?

wallpapers News 2021-06-04
Inside each electric car is a battery that produces a certain voltage.
Considering that this voltage may not be applicable to the various devices being driven, we need to install another device along the signal path.
The device is called a DC-DC Converter, and without it, the modern electric car would not have been possible.
Why do I need DC-DC Converter?
Although DC-DC Converter can be based on many different designs, the basic functionality is the same. We may be talking about a step-up converter that changes the low voltage input to the high voltage output, or vice versa.
The battery of an electric car usually produces a DC voltage of several hundred volts. However, the voltage requirements of the electronic components within the car vary, and most operate at much lower voltages. This includes radio, dashboard readings, air conditioning, built-in computer and monitor.
In an electric vehicle using a DC motor, the actual running of the motor can use up to three times the voltage provided by the battery. With the help of the converter on the right, we can bridge this gap without resorting to a larger, prohibitively heavy battery.
DC/DC converters constitute a complete subclass of electrical engineering. There are many different ways to do a job, all of which are based on the principles of Ohm's Law.
The simplified step-down converter can smooth out this consistent DC signal by generating a series of switching pulses and then using a combination of inductors and capacitors, where the current is constant and the voltage is determined by the duration of the duty cycle (which is "in" relative to the "off" state).
What is the difference between AC-DC Converter and DC-DC Converter?
The plugin your home outputs alternating current, which oscillates between positive and negative relative to each other. In the United Kingdom, the wall voltage is about 230V and the frequency (the rate of current alternating) is 50Hz.
In the United States, the voltage is half that and the frequency is slightly higher, at 60Hz.
Most of the appliances in your home run on direct current, not alternating current. So they carry a special box called a rectifier.
The device performs essentially the same function as a step-down DC-DC Converter, except that it clips the negative part of the input signal through a series of diodes.
The resulting positive wave can be smoothed to the desired voltage by using a combination of inductors, capacitors and resistors.
