<p>very high voltages are needed, for example in <a href="page.php?w=high-voltage_direct_current">high-voltage direct current</a> power transmission).</p>

<p>The pulsating DC voltage results from the differences of the instantaneous positive and negative phase voltages , phase-shifted by 30°:</p>

<p>The ideal, no-load average output voltage  of the B6 circuit results from the integral under the graph of a DC voltage pulse with the period duration of  (from 60° to 120°) with the peak value :</p>
