DC DC Converters: VE-B61-MW-F3 Application Field and Working Principle

DC-DC converters are used to transfer energy voluntarily between two DC sources, producing a DC voltage source which is lower or higher than the original supply voltage. VE-B61-MW-F3 is a type of non-isolated buck type DC power converter. It is capable of providing a wide range of output voltages and small size and highly reliable performance. This article will focus on its application field and working principle.

Application Field

VE-B61-MW-F3 is applicable to output voltage application, which is lower than 30V. It has excellent line and load regulation, which can meet the needs of many demanding applications. Its excellent efficiency guarantees its ability to keep a steady, stable output voltage. Therefore, it is commonly used as the power supply for low voltage applications, such as laptop computers, modems, audio amplifiers, power monitors and other 300W power supplies.

Working Principle

VE-B61-MW-F3 employs non-isolated buck type DC power converter. Non-isolated buck converter is a widely used DC to DC Buck converter. It consists of an inductor, a diode, a capacitor and two transistors. The main working principle is that two transistors control the input and output voltage, while the inductor and capacitor are used to control the current and voltage of the output.The input voltage is rectified by the full-bridge rectifier to the DC voltage, then this voltage is converted to smaller voltage by the two switches which are controlled by the sensing circuit. The sensing circuit monitors the output voltage and accordingly shifts the duty cycle of the transistor, to control the output voltage. The current flows through the inductor which reduces the voltage amplitude. As the current passes through the diode, the voltage is stabilized by the capacitor, and the output voltage is finally obtained.

Conclusion

VE-B61-MW-F3 is a non-isolated buck type DC power converter. It is applicable to output voltage applications lower than 30V. It has excellent line and load regulation, providing efficient and reliable output voltage. Its working principle consists of rectification, two controlled switches, induction, diode and capacitor, thereby controlling the output voltage. VE-B61-MW-F3 is a reliable and efficient power supply for its many low voltage applications.
