Periodic Average
Purpose
Periodically average input signal over specified time
Library
Control / Filters
Description
This block periodically averages a continuous input signal over the specified
averaging time
. The output
is updated at the end of each averaging period.
Mathematically, this block corresponds to a moving average filter where the output is
processed by a zero-order hold:
However, the implementation of Periodic Average filter is computationally less expensive and more accurate than the continuous Moving Average filter.
The block is suited to determine average conduction losses of power semiconductors. To determine average switching losses, use the Periodic Impulse Average.
Parameters
- Averaging time
- The length of the averaging period (in sec.) and the sample time of the output signal. See also the Discrete-Periodic sample time type in section Sample Times.
Probe Signals
- Input
- The input signal.
- Output
- The filtered output signal.
