DC DC Converters are a vast industry, that covers many technologies to convert electrical power from one voltage to another. VI-21V-IV application field and working principle are studied often, due to their widespread usage in many industrial applications.

VI-21V-IV stands for Voltage Injector Variable Voltage Variable Current which is a type of step down DC to DC converter. Most step down converters, utilized a rotating device to convert the voltage. The VI-21V-IV converter is a unique type of step down converter known as a static step down converter. It uses electronic components in a static configuration, rather than a rotating one, to convert voltage.

The application field for a VI-21V-IV converter is broad. These converters are often employed in power-supply systems that require stable output voltages and currents. These converters are also used in varies automotive applications, such as single board computers, digital displays, audio systems, and other mobile devices, since these applications must utilize minimal circuit space and efficiency.

The working principle of a VI-21V-IV converter is straightforward. The first stage of any voltage converter is boost technique, which is used to smoothly increase the input voltage to the desired output voltage. This is achieved by controlling the inductors and capacitors with transistors. Then, the output voltage is stabilized by employing a dedicated closed-loop control circuit, which utilizes different firing angle values and MOSFETs to control the output voltage. Additionally, the current protection and the frequency control of the switching frequency are provided to make the system secure and reliable. After all these operations, the output voltage and current levels are set to the desired ranges and the output is presented with suitable precision.

In summary, VI-21V-IV converters are a static DC to DC converter, which are often utilized in many industrial and automotive applications, where power supplies must be stable and efficient. Moreover, these converters are utilizes in applications which require minimal circuit space. The working principle of a VI-21V-IV converter is that it first boosts the input voltage, then stabilizes the output voltage with a closed-loop control circuit and sets the output current and voltage to the desired ranges by employing different firing angles and MOSFETs.
