5.2 Running the Line and Load Testplan
The line and load regulation testplan is custom built for the schematic being tested when you execute the schematic menu . This testplan is also designed to accommodate multiple input sources and output loads. The testplan contains all tests required to check every input voltage and output load combination. For this reason, no test selection dialog appears at run time and DVM runs the entire testplan.
To run this testplan, execute the schematic menu: .
The line and load regulation data are presented in the Calculated Results section of the overview test report as shown below.
Note: In this particular report, the converter enters the current limit at low line at 100%
load. Thus the measured results for the Line and Load Regulation (Input 1, Output1 )
are much higher than expected. To verify this, reduce the maximum output current from 1.5
to 1.45A (see 3.1.6 Setting Control
Parameters); the resulting line and load regulation values will then be as
expected.
