Working Principle of the VI-21V-MW-F4

The VI-21V-MW-F4 is a fly-back DC-DC converter that uses pulse-width modulation (PWM) control. It consists of a transformer, two power transistors, an input filter and output filter, output rectifying/smoothing section, and control circuit.

With input AC power, the primary side of the transformer carries the PWM pulse signals from the control circuit. The voltage of this PWM pulse is controlled by an onboard operational amplifier or the externally applied feedback signal. The voltage on the secondary side is stepped down, rectified and regulated according to the demand of the load which is connected to the output end of the VI-21V-MW-F4.

The VI-21V-MW-F4 provides adjustable output voltage at very low cost. It is also capable of providing high efficiency and low ripple current output, which makes it suitable for many applications. The VI-21V-MW-F4 provides excellent protection features, such as over-current protection, overload protection, and short-circuit protection. It also provides a wide input voltage and current range.

In short, the VI-21V-MW-F4 is a reliable and efficient DC-DC converter that is widely used in a variety of applications. It provides a high-quality power source at very low cost and is easy to maintain. The VI-21V-MW-F4 is a valuable component that allows users to easily convert AC power into the DC power required for their application.
