Introduction to DC DC Converters
DC/DC converters are devices that are used to convert an applied DC voltage to the desired output voltage. This is often done to match the output of a power supply to the requirements of an electrical device or system. In addition, DC/DC converters can also provide power conditioning, such as allowing low voltage power sources to step up their voltage to provide enough power for the desired load.

How it Works
The V28A15H200BF converts an applied DC voltage to the desired output voltage through the following steps:Step 1: The V28A15H200BF input voltage travels through the input capacitors and then is rectified in the full-bridge rectifier.Step 2: The rectified DC voltage is filtered by the output inductor/capacitor filter.Step 3: The filtered DC voltage passes through a PWM power converter with a pulse-width modulation (PWM) technique. The switching frequency and duty cycle of this converter is adjusted based on the output voltage requirement. Step 4: The PWM output is filtered by the output inductor/capacitor filter before being rectified in the secondary rectifier. Step 5: Finally, the filtered DC voltage reaches its destination as the output voltage.
