DC/DC converters are essential in electronic systems, providing efficient and reliable means of transforming and safely transferring power. An essential part of this is the VE-BT1-IV-F4, a series of isolated voltage converters designed to provide a constant voltage output with low noise ripple. This article will discuss the application field of and working principles behind the VE-BT1-IV-F4.

Application Field

The VE-BT1-IV-F4 is designed with the specific applications of medical, industrial, automotive, electrical and electronic equipment in mind. Its isolated configuration offers the highest levels of system security and safety, while its range of input and output voltages enable circuit designs for almost any application. It is ideal for use in commercial and industrial settings where it can provide input and output voltages as high as 600V and as low as 1.5V. It also features a wide operating temperature range between -40°C and +105°C and is designed with an ultra-wide input voltage range of 4.5V to 24V, making it suitable for use in extreme environments. With its low ripple noise of <100mV and high power density, the VE-BT1-IV-F4 can effectively supply the needed amount of power for many applications.

Working Principle

In general, the VE-BT1-IV-F4 is a type of switch-mode power supply that uses a magnetic field-based switching mechanism to convert energy from the input power source to a desired output voltage with a fixed frequency. The device comprises of a bridge rectifier which typically consists of four diodes arranged as a full-wave rectifier. The rectifier then converts the input AC voltage into a DC voltage, which is then fed to a filter capacitor to maintain the DC voltage and eliminate any AC ripple noise. This DC voltage is then further regulated using the switching mechanism, which typically consists of a MOSFET (metal-oxide-semiconductor field-effect transistor) to regulate the output voltage along its range. The MOSFET operates in a PWN (Pulse Width Modulation) or switching control mode, where it switches the power supply on and off at regular intervals, creating pulses of varying width to achieve the desired output voltage. The output voltage is then further regulated using an opto-coupled feedback circuit for constant voltage regulation.

In summary, the VE-BT1-IV-F4 is an isolated voltage converter designed for use in medical, industrial, automotive, electrical and electronic equipment. It is ideal for use in extreme environments and provides a wide input voltage range of 4.5V to 24V, with an operating temperature range between -40°C and +105°C. It has an extremely low ripple noise of <100mV and its working principle relies upon a bridge rectifier for DC conversion and a MOSFET, operating in a PWN control mode, to regulate output voltage. Furthermore, an opto-coupled feedback circuit is also used for constant voltage regulation.
