<strong>The</strong> <strong>Electronic</strong> <strong>Load</strong><br />
Example 5<br />
CF = 5, phi: 45° leading<br />
Current and voltage are phaseshifted.<br />
<strong>The</strong>re are still no ranges in<br />
which the power curve becomes<br />
negative.<br />
<strong>The</strong> load can still reflect this<br />
case.<br />
Result<br />
Phase shifts are only possible in<br />
combination with a setting of<br />
the crest factor to values >1.41.<br />
<strong>The</strong> greater the crest factor (the<br />
narrower the current pulse), the<br />
further one can shift the phase.<br />
Phase shifts with sinusoidal<br />
currents as with inductive or<br />
capacitive loads are not possible<br />
because with each phase angle<br />
deviating from 0° there would<br />
have to be energy flow into the<br />
source.<br />
Example 6<br />
CF = 5, phi: 70° leading<br />
Current and voltage are phaseshifted.<br />
<strong>The</strong>re are ranges in<br />
which the power curve becomes<br />
negative. In this case the<br />
electronic load would have to<br />
generate power.<br />
<strong>The</strong> load cannot reflect this<br />
case.<br />
