RECOM: Your One-Stop Shop for Power Supply Solutions

Modern electronic equipment requires the careful design of its power architecture to optimize cost, efficiency, and size. Within a system, it is common to deploy one or more AC/DC power supplies followed by isolated DC/DC bus converters and downstream switching regulators acting as Point-of-Load (PoL) converters. Additionally, isolated DC/DC converters are frequently utilized to provide auxiliary voltage rails of varying polarities and combinations, typically to power isolated communication or sensor interfaces.

Procuring all these various converters from different sources introduces a clear risk, as there is no guarantee of compatibility between parts. Additionally, if the system does not work as expected, suppliers may claim that other vendors are to blame.

An example of this is a failed EMC report: individual parts may comply with standards on paper under set conditions, but when coupled with other converters under real-life conditions, statutory limits for conducted or radiated emissions are exceeded. Other compatibility issues can arise from loop instability introduced when driving one switching converter from another. Differences in product data sheet measurement methods, such as temperature rise, can also lead to confusion; for instance, definitions of ambient temperature and where it is measured can vary significantly between suppliers.

The solution to all this is to rely on RECOM for your power conversion needs. We support you from initial system design and product selection through to debugging and assistance with the EMC qualification of your end product.

Shifting to Distributed Power Architecture (DPA)

Having a single system power supply that generates all of the voltages needed in a product is now an outdated concept due to increasingly tight specifications for critical power rails and the need to maximize efficiency while minimizing cost and size. This has pushed system designers toward the Distributed Power Architecture (DPA) approach. Typically, an optimized AC/DC converter with integrated power factor correction generates a common bus voltage—such as 12V, 48V, or even 400V in data centers—allowing power to be distributed at lower currents with fewer consequent resistive losses.

Downstream DC/DC converters drop the voltage to a lower-level bus, after which Point of Load (PoL) converters provide high current rails close to the loads for optimal static and dynamic regulation. The DPA approach optimizes efficiency, distributes the heat load, and offers excellent flexibility—allowing for relatively easy upgrades, re-configuration, and isolation of different subsystems. Overall costs can also be lower, as standard modules can be utilized with specifications chosen to meet your exact requirements.

The Hidden Risks of Multi-Vendor Integration

However, problems can arise when system modules are procured from different sources, even if they are reputable. Products are characterized in their data sheets under specific conditions that often differ from one manufacturer to another. Temperature rating is a prime example—some parts are characterized by a maximum hot-spot temperature on their case, while others limit ambient temperature measured at an arbitrary distance from the converter. Similarly, the orientation of converters during derating characterization can vary, with some measured on a horizontal PCB and others with the PCB positioned vertically.

EMC performance can also be problematic, as suppliers are forced to assume external conditions—such as supply impedance—when measuring conducted and radiated emissions. Converters can also interact with each other through magnetic or electrical noise coupling along connections, which varies depending on product orientation. Furthermore, on-board filters that make an individual part compliant with an EMI specification on paper can combine with filters in other products to actually worsen overall EMI. This is typically due to unintended resonances and consequent voltage peaking.

A particularly insidious interaction occurs when a regulated switched-mode converter is fed directly from the output of another. Assuming constant efficiency and output load, the input power to a regulated switching converter remains constant; thus, if the input voltage increases, the current decreases, creating a negative resistance effect.

An upstream regulated converter is typically characterized for standard positive resistive and capacitive loads, meaning it can easily become unstable when subjected to this negative resistance. Similarly, a positive voltage transient from the upstream converter will cause a decreasing current in the downstream converter. This can trigger the control loop of the first converter to push the voltage even higher, amplifying the original effect to potentially damaging levels.

Mitigating System Instability with a Single Trusted Source

Parts interacting in these ways are not necessarily faulty, but individual suppliers may be reluctant to fix a problem if they see that other vendors are involved. For this reason, it is advisable to procure components from one trusted source who takes responsibility for ensuring all supplied parts work together as intended.

While it is impossible to guarantee that no compatibility issues will ever arise with every conceivable combination, a single-source supplier like RECOM has the resources to assist with initial system specification, module selection, and the resolution of any difficulties. For example, RECOM offers a dedicated range of filter components evaluated specifically alongside our power conversion products, which can be paired on evaluation boards to verify overall system EMI performance. Furthermore, our specialized EMC test facilities are fully available to RECOM customers to help debug system-level issues and perform reliable pre-compliance testing.
