Worked Example

Verified calculation

Given:

  • Collector Current = 50
  • Junction Temperature = 343.15
  • Zero-Temperature On-State Voltage Offset = 1.8
  • On-State Resistance = 0.0025
  • Voltage Temperature Coefficient = 0.002
  • Reference Junction Temperature = 343.15

Expected Result:

  • Conduction Power Loss = 96.25

Engineering Interpretation:

Under the given input conditions, the calculated result is: Conduction Power Loss = 96.25 W.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method
