Power distribution and management are crucial elements of many different electrical systems, from electric vehicles to data centers. When designing power systems, engineers need to optimize efficiency, minimize the space and keep costs down. These often competing requirements present significant challenges to power system designers.Additionally power engineers are faced with shorter development timeframes than ever before and still must toil with changing system specifications throughout the project.
Andy Gales, Vice President of International Sales focused on India and South Africa and Head of WW Sales Enablement of Vicor Corporation Ltd spoke to Vaishali of Electronics Maker about power system design challenges in today’s fast-paced economy. Gales shared new insight on the difficulties that engineers face based on Vicor’s recent study of 822 engineers. Gales identifies predominant problems and explains how some designers are adapting to the challenges.
What is stressing power design engineers?
- Time to market pressures- 80% of power engineers are already struggling to meet time constraints when designing power systems and 79% feel that project schedules are tighter due to time-to-market pressures. New specification changes exacerbate this pressure, and are among the most significant problems they face
- Late-stage changes- The top power design challenges identified by engineers are downstream changes to the specifications after the design process has begun. According to research conducted by Vicor Corporation, 87% of power system designers around the world identified specification changes as the most frequent impediment in designing power systems.

Adapting to today’s business pressures and power design demands
A change to specifications after development has started is problem for designers and they feel it is getting worse. Conventional approaches to power system design, using discrete components, were developed when specifications were less fluid. Discrete designlacks flexibility, which makes adapting to the changes difficult, time-consuming and expensive.
When creating power system designs, engineers need to consider more flexible approaches to contend with specification changes. For example, the Power Component Design Methodology enables engineers to easily swap out different components in their power design with minimal risk to project schedules.
Using modular power components offers greater flexibility over a discrete approach. The modular approach makes modifications to power systems quick and easy, making it far more effective in today’s unpredictable design environment. The Power Component Design Methodology is a proven, low-resource, low-risk approach to high-performance power Subsystem design. Unlike other approaches, the Power Component Design Methodology is a complete, holistic system that covers the entire power supply from power entry (source) to PoL
(point of load).
A modular approach is better for business
Vicor’s Power Component Design Methodology enables power system designers to reap all of the benefits of modular power component design:
- predictable component and system functionality
- fast design cycles
- easy system re-configurability-configurability and scaling
At the same time it delivers optimal system operating efficiency, power density and economy that rival the best alternative solutions. UsingVicor’s online tools, power system designers select from an extensive portfolio of proven Vicor power components to architect, optimize and simulate their complete power system, all the way from their input sources to their points of load.
This innovative approach to power system design delivers fast time-to-market and state-of-the-art performance, while minimizing delays that so often occur with conventional or custom design methodologies.
