We asked one of our lead engineers, what are the essential questions you ask when designing a custom power transformer?
He broke down these questions into five primary categories that cover 90% of the applications
1 – The Type of Transformer
What type of transformer does it need to be? The most common are:
- Single Phase
- 2-Phase
- 3-Phase
Don’t worry; we specialize in the not-so-common types as well.
2 – Primary (The Input Section)
- What is the input voltage?
- What is the input current?
3 – Secondary (The Output Section)
- What is the desired output voltage?
- What is the desired output current?
If the secondary is DC, what is the rectifier topology? The most common are:
- Full Wave Bridge
- Bridge
- Center-Tapped
- Single Phase
4 – Finish (The Connectors)
What type of connectors do you need for your application? The most common are:
- Wire leads
- Terminal Block
- Solder Lugs (Used primarily on PCB boards)
- Copper Terminals
5 – Geometry (The Size)
What is the desired size or the space restrictions of the transformer?
In more complex applications, there may be a few other considerations categories to discuss, such as:
Regulation
The voltage regulation of the transformer is the percentage change in the output voltage from no-load to full-load. Voltage regulation will vary as the power factor varies. The regulation is measured in percentage.
Temperature
- What is the ambient temperature range the power transformer will be working within?
- What is the maximum allowable temperature rise?
- Will there be any cooling?
Testing
Some applications will require additional testing to receive a particular certification. For example, many transformers built for defense require a MIL-SPEC certification, which subjects random samples to vibration testing.
Regardless of your project’s complexity, our engineering team has the expertise to design the ideal solution for your application.
