DC-DC converters provide power that has been converted from one form of DC to another. They provide a variety of voltage levels and power management solutions and can be used in a variety of areas. This article will discuss the application field and working principle of the VHK75W-Q24-S3R3-DIN DC-DC converter.

The VHK75W-Q24-S3R3-DIN is a wide input voltage range, non-isolated DC-DC converter designed for various automation, industrial, and transportation applications. It has an operating input voltage between 3.3 and 24V. With an output voltage of 5V, it is suitable for common 5V electronic systems. The robust design of the module provides noise immunity and efficient output performance in a wide range of operating conditions.

The VHK75W-Q24-S3R3-DIN also has a built-in overvoltage protection circuit against output overload, as well as full-load input/output overvoltage protection. This prevents components from being damaged in the event of a power surge or dropout. Other protection functions include over-temperature protection, undervoltage lockout, and an overcurrent protection circuit.

The working principle of the VHK75W-Q24-S3R3-DIN is based on a switching regulator, which operates with switch circuits and feedback control circuits. A switching regulator uses transistors, FETs or other switch devices to periodically transfer energy from the input to the output. This process is known as buck-boost topology. The switching regulator is capable of maintaining the output voltage at a constant level regardless of changes in the input voltage.

The frequency of the VHK75W-Q24-S3R3-DIN is determined by the components in the circuit and the feedback control circuits. These components are designed specifically to meet the operating conditions of the module. The frequency is typically in the range of several kilohertz. The switching frequency is used to control the amount of energy transferred from the input to the output.

The output of the converter is regulated using a PWM (Pulse Width Modulation) technique. This technique uses a set of pulses to regulate the output voltage by gradually varying the widths of the pulses. This variations control the power transferred from the input to the output. Thus, the output voltage is regulated and kept constant over a given range of input voltages.

In summary, the VHK75W-Q24-S3R3-DIN is a wide input range non-isolated DC-DC converter designed for various industrial and transportation applications. It has a robust design with built-in protection circuits, including overvoltage, over-temperature, and overcurrent protection. The converter works on the principle of switching regulator and PWM techniques, which are used to regulate the output voltage over a given range of input voltages.
