AUTOMATIC BALANCE CORRECTION CIRCUIT FOR A BALANCED CURRENT CHOPPER |
摘要 |
<p>An automatic symmetry correction circuit is provided for a symmetrical current chopper. This structure includes two current channels controlled alternately by two signals of frequency f. A resonant LC circuit is tuned to the frequency f and energized by the currents passing through each of the two channels. A control circuit is coupled to the resonance circuit for adjusting the symmetry between the amplitudes of the currents flowing through each of the two channels as a function of the amplitude of the oscillations of frequency f generated by the resonance circuit.</p> |
