Working Principle of VI-264-EV DC-DC Converters

The VI-264-EV DC-DC converters use a full bridge topology, with high-voltage DMOS series devices to reduce the power dissipation. The input voltage is rectified and an appropriate voltage rail is formed by the pre-regulator. A synchronous buck-based step-down voltage regulator is used to reduce voltage from the input voltage to the desired output voltage. A feedback loop is used to control the output voltage and regulate the switching frequency. The output voltage is passed through a low-pass filter for noise reduction. The MOSFET switch then converts the DC voltage to an AC waveform, every cycle the current rises as it charges the inductor, and then as it passes through the diode. The voltage is then converted back to DC as it passes through the capacitor.
