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
