BB-MDR-20-5

AC DC Converters provide an efficient power conversion system for numerous applications across virtually all industries. One such type of AC DC Converter is the BB-MDR-20-5, which is a series-resonant converter designed for power systems ranging from 20W to 50kW.

The BB-MDR-20-5 is suitable for many types of applications due to its wide input voltage range, low input current ripple, no-load operation, and high efficiency. It is used in a variety of applications, such as aerospace, automotive, medical, industrial, telecommunications, and consumer electronics.

The working principle of the BB-MDR-20-5 is based on the series resonant topology. This topology is a combination of boost, buck, and flyback topologies. The boost topology is used for start-up, the buck topology is used for DC/DC isolation, and the flyback topology is used for DC/AC conversion. The working principle of the BB-MDR-20-5 is described in the following points:

• In the boost topology, the input voltage is raised by a certain factor so that the voltage required for the output can be generated. The output voltage is regulated by a feedback control loop.
• In the buck topology, the input voltage is reduced by a certain factor so that the voltage required for the output can be generated. The output voltage is regulated by a separate feedback control loop.
• In the flyback topology, the input voltage is converted into a high frequency AC voltage which is then rectified and filtered to generate the output voltage.
• The output voltage is regulated by an adjustable reference voltage.

The BB-MDR-20-5 has numerous advantages over traditional AC/DC converters, such as higher efficiency, smaller size, less EMI, better electromagnetic compatibility, and low input current ripple. Additionally, it has an improved dynamic response and a wide input voltage range.

In conclusion, the BB-MDR-20-5 is an ideal choice for numerous applications due to its wide input voltage range, high efficiency, and no-load operation. Furthermore, its small size and low current ripple make it an ideal solution for various industries.
