SynQor Parallel Chart - This chart is a quick
overview of the feasibility and method to achieve current sharing when connecting
SynQor converters of a given product or family.
Start-up with Varying 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.
Thermal Resistance Explanation - This application note describes
the thermal resistance of SynQor's DC-DC power converters for open frame and baseplated
or encased units.
Hi-Pot 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.
Series Operation of SynQor Converters - 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.
Compliance - This application note describes which SynQor converters
and filters have been tested in conjunction for compliance with MIL-STD-461 for
the control of EMI in military systems. A breakdown of the individual requirements
within the specification and the compliance of SynQor modules to each is provided.
Mil-COTS 270V Full Feature - This application note
explains how to implement the features of a Full Featured Mil-COTS 270V converter.
Features include active current sharing, clock synchronization, and start-up synchronization.
These items are explained in detail and layout suggestions and wiring schemes are
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.
System Instability - This application note details the condition
of input system instability that can occur because a DC-DC converter appears incrementally
as a negative resistance load. The note provides an understanding of why this instability
arises, and shows the preferred solution for correcting it.
Load Current Calculations - This application note provides a simple
method to calculate the output load current using the current sense resistor found
on SynQor's open frame DC-DC converters. All equations, turns-ratio and sense resistor
values are included for the calculations.
Output Voltage Ripple Measurements - This application note explains
the existence of occasional high frequency noise spikes when measuring the output
voltage ripple on a SynQor converter and how these spikes are largely a measurement
artifact. The paper details how to eliminate this measurement error with the proper
test set-up and termination methods.
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 using a single thermally relieved via.
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.
Explanation of 100V Input Transient Protection - This application
note provides an overview of SynQor's input transient protection features and explains
the differences in protection ratings across our DC-DC converter product lines.
It also answers some frequently asked questions concerning these features.
Aqueous Cleaning and Soldering Considerations - This Application
Note provides an overview of Aqueous Cleaning and Soldering Considerations for SynQor
Open-Frame, Fully Encased, and Base-Plated Products.
