Improvement of software reliability is a pressing issue in the digital control of power electronics. It is commonly reported by managers and executives in large power supply purchasing OEMs that most of the issues with power supplies are due to software problems.
Improving software quality for digital power
As part of an initiative by the Power Supply Manufacturers Association (PSMA) Reliability Committee, ELMG Digital Power provided research, examples and written material for the PSMA Software Firmware Reliability Improvement Report.
Typical issues in digital power electronics
Typical issues in digital power electronics include
- Limited modulator precision due to timer and clock speed
- Numeric precision limits in digital filters
- Excessive delays from limited processing power
Software quality improvement
As software quality is the result of following and implementing a repeatable process the report details how
- Version control
- Code standards
- Defect tracking
- Code reviews
- Code inspections
- Inspections before testing
- Test specifications
are used to improve code quality.
How do you get the report?
Best way to get the report is to join the PSMA or you can purchase it.
