DC DC ConvertersDC DC converters are electronic power devices which convert a direct current from one supply voltage to another. They are used to produce a higher, lower, or isolated output voltage from a direct current source. The V72B28H250BN is a DC DC converter used for a variety of applications.This converter is a two-stage, isolated DC-DC switching converter, and is composed of a transfer unit and a power unit. The transfer unit is a Pulse Width Modulation (PWM) topology, while the power unit is a Resonant Zero Voltage Switching (RZVS) topology. This device is suitable for a range of different applications such as medical devices, industrial controls, instrumentation, data storage equipment, communications, industrial automation, embedded systems, and automotive applications.The power achieved with this device is impressive, with a rated power output of 250 W and a peak power output of 270 W. The DC input range is 9.5–36 V, and the switching frequency is 350 kHz. It features a remote on/off, enable/disable, and a logic control function, and includes an adjustable output voltage. The output voltage range is 1.2-14.4 V, with a accuracy of ±2.5%.The working principle of the V72B28H250BN is based on the Pulse Width Modulation (PWM) technique over two-stages. The transfer unit is the first-stage switching, which includes the PWM generator, gate driving circuit, power transformer, and a power MOSFET. The resonance-type power unit is the second-stage switching. The power unit works by providing the PWM signal to the transformer primary. The transformer then converts the AC to a DC voltage which is sent into the output filter then rectified to the desired output.The V72B28H250BN offers an extremely high power density, low output ripple and low gate stress, making it an excellent choice for a variety of applications. It is robust and reliable, making it perfect for military, aerospace, medical, and industrial conditions.Finally, thanks to its advanced design, the V72B28H250BN is incredibly efficient. It can maintain its high efficiency whether it is operating in a well-ventilated environment, or in adverse conditions. This converter is an excellent choice for demanding applications, and can be used with a wide range of input and output voltages. In addition, it can be controlled remotely with a potentiometer to adjust the voltage output.
