Custom Power Supply Design

Whether the power supply you need is a low cost desktop application, or a high reliability medical or industrial supply, O'Grady Engineering has the expertise and experience to help you achieve your power supply design goals.

We can take your product from concept to production. We pride ourselves on rugged power supply designs, and satisfied customers. To achieve this we will work with your engineering staff to assure the power supply design you get will meet or exceed your specifications. We routinely make cost cutting suggestions, or advise on ways to increase reliability without adding to costs.

In order to meet the design goals of our customers, and provide them with an optimized custom power supply design, we employ the following standards and software:

Topology Selection
Proprietary Excel and MathCAD based software is used to assist us in determining which of the many power supply topologies is best able to meet the customer's requirements.

Parts Stress Analysis
Proprietary Excel based parts analysis software is used to determine the stress imposed on each part in the design. Unless otherwise specified by the customer, we design to the recommendations of the Department of Defense Reliability Analysis Center (RAC). We also use the design practices set forth in the Navy Power Supply Standard NAVSO P-3641A.

Parts Optimization
It is important in any electronics design that the parts in the design are optimized for their application and that their values are centered. To accomplish this we use a combination of mathematics solutions and spice circuit simulations to verify each circuit's operation.

Design Reliability
When requested by the customer we can run a design reliability analysis to Mil-Hdbk-217 or Belcore standards. We use Relex reliability software version 7.1

Bench Test Verification
Every power supply we design undergoes extensive circuit verification on the test bench. Operating points and loop stability are verified and provided to the customer.

Thermal Analysis
Thermal part stress is a part of the design process, and is verified during bench testing of the prototype power supply.

Schematic Generation
Schematic documents are generated using P-cad version 2002 software.

PCB Design
PCB artwork is generated using P-cad version 2002 software.

Parts Lists
We supply our customers with a complete Excel based parts list.
