Application Notes

Start-Up into Capacitive Loads

This application note describes the start‑up characteristics of SynQor converters starting into loads below, near and above the output capacitance limits on the datasheet.

SynQor Series Operation

This application note describes how to connect isolated DC‑DC converters in series to create non‑standard voltages for the industrial market. Wiring diagrams and design considerations are provided for series operation of multiple DC‑DC converters.

Thermal Relief Study

This application note addresses concerns raised with regards to pin and board heating when high currents (>60A) are driven through thermally relieved plated through hole (PTH) vias. Detailed thermal analysis will show that internal heat generation and resulting temperature rise of the power converter and load board is minimal when… Read More

Current Sharing on Full Feature Modules

This application note details the additional features available in SynQor’s full-feature converter modules. There is substantial information provided to facilitate the use of the active current sharing feature for N+1 and parallel applications.

EMI Characteristics

This application note provides an overview of electromagnetic interference (EMI), the different standards and regulations, how these standards and regulations relate to DC-DC power modules, suggestions for external filtering solutions, and suggested layout and grounding practices.

ACuQor Hipot Balancing

This application note describes the correct method for hipot testing the ACuQor series of AC‑DC converters. The note provides an understanding of the difference in capacitance values from input‑to‑ground and from output‑to‑ground as well as a solution for balancing the voltage stresses.
