DC-DC converters are a type of power supply device that converts electrical power from one voltage to another. They are used in many applications such as regulating voltage, providing isolation, transforming voltage levels and controlling speed or direction of rotation in motors. The VQB75W-Q24-S15 DC-DC converter is a device designed for power systems that require regulated, galvanic-isolated voltage outputs in the range of 5 V to 14 V. This converter consists of four major components:

• Input power stage: This consists of an DC input filter, surge protection, an input rectifier, an isolation transformer, and a power factor correction component.
• Voltage Regulation Stage: This stage provides output voltage regulation and includes a linear controller to transfer energy from the input to the feedback winding of an isolation transformer. This stage also contains compensation circuits to reduce output voltage ripple.
• Isolation Stage: This stage provides galvanic isolation between the input and output terminals of the converter. The power factor correction component is incorporated into this stage.
• Output Stage: This stage controls the electrical characteristics of the output voltage waveform and includes an output rectifier, output filter, and post regulator.

The working principle of the VQB75W-Q24-S15 DC-DC converter is based on the “Boost-Buck-Flyback” switching technique. This technique involves the transfer of energy from the input to the output in three steps. First, the Boost power converter, also known as the power factor correction (PFC) stage, rectifies the input line voltage which is then switched to a Buck converter stage. The Buck power converter efficiently boosts the voltage and increases the output power. Finally, the energy is transferred from the Buck converter stage to the output via an isolated energy transfer, accomplished using an isolation transformer, in the Flyback stage.

The VQB75W-Q24-S15 DC-DC converter is used in a wide range of applications, including industrial automation and machine control systems, railway systems, computers and telecommunications equipment, industrial power systems, inverters, LED lighting products, and automotive applications. In industrial automation and machine control systems, the converter is used as a power supply for solenoids, relays, servo motors and industrial process controllers. In railway systems, the converter is used to provide power for lights, emergency circuits, traction systems and signals. It is also widely used as a power supply in computers, telecommunications equipment, and LED lighting. In automotive applications, the converter is used to power vehicle audio systems, navigation, electronic control units and lighting systems.

In summary, the VQB75W-Q24-S15 DC-DC converter is a power supply device that converts electrical power from one voltage to another. It is used in many applications such as providing voltage regulation, galvanic isolation, power factor correction, and controlling speed or direction of rotation in motors. This converter is based on the “Boost-Buck-Flyback” switching technique and is widely used in industrial automation and machine control systems, railway systems, computers and telecommunications equipment, industrial power systems, inverters, LED lighting products, and automotive applications.
