V28C3V3H50BL Working Principle

The V28C3V3H50BL module works on the principle of switching regulators that convert input voltage to an output voltage through an inductor and capacitor stage. The output voltage is regulated by the feedback circuit, which monitors the voltage and ensures it stays within the desired range.

First of all, the input voltage is converted to an AC voltage and then rectified. The rectified AC voltage is then filtered and fed to the switching circuit. The switching circuit is designed to turn on and off the power transistor according to a specific set of logic to control the output voltage. This is done by sensing the output voltage and comparing it with the desired voltage. If the output voltage is lower than desired, the switching circuit will turn the power transistor on or increase the duty cycle to boost the output voltage.

On the other hand, if the output voltage is higher than the desired voltage, the switching circuit will turn off or reduce the duty cycle of the power transistor to reduce the output voltage.

The output voltage of the V28C3V3H50BL module is stabilized by the error-amplifier circuit and the feedback loop. The error-amplifier compares the output voltage with the reference voltage and generates an error voltage. This error voltage is then fed back to the switching circuit to control the output voltage.
