DESIGN PHASE: measurement SUB ELEMENT NAME: photo measurement - snubber waveform measurement VARIABLE NAME: [HEMTSNUB] DATE: REVISION LETTER: REVISION DATE: APPLICABILITY: switching mode circuits ACTIVITY: Measure (oscilloscope photographs) snubber waveforms and measure snubber losses and effectiveness. OUTPUT: Labeled photographs in laboratory notebook and measured (or calculated from measurements) value of snubber losses. ALGORITHM: [HEMTSNUB] = engineer hours to measure snubber characteristics [HTMTSNUB] = technician hours to measure snubber characteristics 1.0* hours per snubber [NPWRXSTR] number of power transistors DISCUSSION:
