Power measurements: Output Analysis algorithms
Power measurements require option 5-PWR or 6-PWR.
Line Ripple algorithm
Line Ripple measures the voltage of a power supply which has been derived from an alternating current (AC) source, displaying
the results as a peak-to-peak value and RMS value. In Line Ripple measurements, the time base is set to display three cycles of
50 Hz or 60 Hz in the input waveform.
Depending upon the coupling type you select, the application sets the required offset and adjusts the vertical scale to the
appropriate sensitivity.
Switching Ripple algorithm
Switching Ripple measures the voltage ripple at operating the specified power supply switching frequency, up to 1 MHz.
Efficiency algorithm
Efficiency measures the ratio of output power to input power for a power conversion circuit. The measurement supports three
outputs, the maximum and efficiency is computed at each output. If there are more than one output, then the total efficiency value
will be computed. You can configure AC/DC type at input and output sides.
NOTE. This measurement uses a minimum of four sources and a maximum of eight sources. Two sources are used to measure
the input voltage and current to the power supply. Two to six sources are used to measure the power supply output voltage and
current.
Math is used to compute Input Power waveform using V * I equation. Computation happens over an exact integer number of
cycles to get an accurate result, that is, from the first zero crossing to the last zero crossing.
Math calculates the Input Power, using
Similarly another math calculates the Output Power using V * I at the output side
Power Efficiency = Output Power / Input Power
NOTE.
■
If more cycles are captured, then the power solution will automatically consider all the integral cycles, starting from first (mid)
crossing to the last valid (mid) crossing.
■
For multiple outputs, the total efficiency is computed as the ratio of input power to the sum of output(s) power. The total
efficiency is expected to be within 100%, since all the outputs are from a same input power. If the efficiency is greater than
100 %, then the application displays a warning message.
