Voltage Regulation Graphs

The following figure shows the load regulation plot of the converter. Both outputs are connected in series and loaded with the electronic load. This ensures identical loading of both isolated outputs. Note that for the no-load condition, the forward voltage of the secondary diodes is practically zero and the output exceeds 17 V. Pre-loading the output with approximately 500 µA brings the voltage significantly lower.
