DC DC Converters

A DC DC converter is an electronic device used to convert a direct current (DC) voltage to another DC voltage level. It is also known as a power converter, voltage converter, or DC-to-DC converter. It is mainly used to step down or step up DC voltages. The VI-20F-IY-S converter is designed to step down an input voltage of 20 Volts to an output of 5 Volts, while also providing the necessary current to drive various microcontroller circuits.

Applications

The VI-20F-IY-S converter is most commonly used in applications requiring low voltage and high current. Examples of these applications include microprocessors, computers, and other electronics. It is also used to power various devices such as LED lighting, motor control, RFID systems, and other power-hungry circuits. In addition, it can be used to convert AC voltages to DC voltages, allowing it to power multiple devices at the same time.

Working Principle

The VI-20F-IY-S converter works by using a step-down converter to reduce the voltage of the input signal. This input voltage is then rectified and filtered in order to produce a constant DC voltage. This DC voltage is then regulated by adjusting the duty cycle of a PWM converter. This adjusts the voltage value to a desired level, allowing for the current to be controlled and provided to the output.

The output current is delivered to the circuit through an inductor and capacitor, ensuring that the intended voltage is delivered. The inductor stores energy and the capacitor maintains a constant voltage level. This ensures that any fluctuations in the input voltage are minimal, allowing for a more stable output.
