DKIT-AC-24-POL-00

Evaluation boards are essential tools used to develop and verify system design and component evaluation. For power supply systems, it is critical to ensure that the DC/DC or AC/DC (Off-Line) switch-mode power supply (SMPS) meets the specified performance and safety requirements. The DKIT-AC-24-POL-00 evaluation board is one such evaluation board, designed specifically to test AC/DC (off-line) SMPS. This article outlines the application field and working principle of this evaluation board.

Application field of DKIT-AC-24-POL-00 evaluation board

The DKIT-AC-24-POL-00 evaluation board is designed to evaluate the performance of off-line AC/DC SMPS. It is specifically tailored for use in isolating end equipment with limited space requirements. Conveniently, this evaluation board is also suitable for applications in residential, commercial, industrial, and LED lighting systems, as well as in similar medium-power AC/DC transformer applications.

Working principle of DKIT-AC-24-POL-00 evaluation board

The DKIT-AC-24-POL-00 evaluation board works by taking an AC/DC input current and using a single-chip zero-voltage-switching (ZVS) AE10P03 IC as the primary stage source. This has the benefit of ultra low switching losses, excellent EMI performance, and improved power supply efficiency. The outputs of the primary stage of the AE10P03 IC are then filtered and rectified through a secondary stage with the help of the C8P03 IC, which is in turn connected to an additional secondary-side filtering stage through an AE10P03 IC again.

The evaluation board also contains a pair of MOSFETs in a half-bridge topology to facilitate the switching of the isolated output with a floating ground terminal. Additionally, the board also allows for the adjustment of the peak adjustment current through the PWM (pulse width modulation) of the input voltage with the help of an AP2112K IC, which provides for a highly precise current control. Finally, the board also includes several other components like resistors, capacitors, diodes and inductors to further improve the performance of the AC/DC transformer.

Conclusion

The DKIT-AC-24-POL-00 evaluation board is a powerful tool for evaluating the performance of off-line AC/DC SMPS. It is specifically tailored for use in isolating end equipment with limited space requirements, and is also suitable for applications in residential, commercial, industrial, and LED lighting systems, as well as in similar medium-power AC/DC transformer applications. This evaluation board works by taking an AC/DC input current and using a single-chip zero-voltage-switching (ZVS) AE10P03 IC as the primary stage source, and further filtering and rectifying the output with the help of other ICs. This evaluation board helps to test and verify that AC/DC (off-line) SMPSs meet the specified performance and safety requirements.
