Working Principle

The VSUU-120-T515B works by converting the incoming AC voltage into DC voltage. This is achieved by using a dual-mode technology to firstly rectify the input AC power, then regulate the voltage output.The AC voltage is first transformed into a single-phase AC waveform by the transformer, then rectified by the diodes. After rectification, the DC voltage is passed through the storage inductor. The storage inductor helps to store the energy and provide a smooth current flow to the main DC regulator. This is where the dual-mode technology comes in, where a power transistor is used to regulate the final output voltage. The regulator monitors the voltage and adjusts the duty cycle in order to achieve the desired output voltage. Finally, the EMI filter reduces nuisance signals which could interfere with nearby equipment.
