Can a reversing circuit cause overvoltage?

Because triggering one reversing circuit does not result in an overvoltage on the spark gaps of other sections, all switches in an LC generator must be actively fired with strong, synchronized trigger pulses. Most applications for pulse modulators require a constant-voltage pulse.

How does the risetime of voltage decrease?

The risetime of voltage decreases gradually as shown in Fig. 2.24, when L 1s ≫ L 2s ≫ L 3s . The fall time at D is dependent on load resistance. When the capacitor, C 1, is charged to nV 0, where n is the amplification factor of the transformer, L 1u shifts to L 1s and, concurrently, the stored energy of C 1 transfers to C 2.
