Working Principle of VOF-100-24

The VOF-100-24 AC/DC converter works on the principle of rectification, or the conversion of AC input into a DC output. The device can be used in either forward or reverse conversion mode to provide a regulated output voltage. This is achieved by using a high frequency switching topology and a PWM or variable pulsewidth modulation technique.

Firstly, the AC input is rectified by the input bridge rectifier, and then fed into a power factor correction (PFC) circuit which helps reduce current loss and distortion. This, in turn, feeds into a voltage doubler network, which is then buffered through a low-pass filter. This output from the filter is fed into the PWM controller, which adjusts the pulsewidth so as to maintain the desired output voltage level.

The output of the controller is then amplified by a power amplifier, and sent to the power stage, which is generally made up of two transistors. This stage produces a DC output, which is then smoothened by an output low-pass filter. Overall, the device is equipped with current and voltage limiting features, over-voltage protection, short circuit protection and thermal shutdown features to ensure safety and reliability.

Conclusion

The VOF-100-24 is a versatile AC/DC converter that is used for a wide range of industrial and commercial applications. It provides high quality power with excellent performance, and is designed to withstand the extreme automotive requirements. Its high frequency switching topology and PWM or variable pulsewidth modulation technique, along with its built-in protection features, make it a popular choice for many applications.
