Fig. 1
Fig. 1: Q801, Q802 and T801 form a full-bridge configuration.
The full-bridge switch is configured such that Q801 N-MOS and Q8026 P-MOS are ON while
Q801 P-MOS and Q802 N-MOS are OFF in a half-cycle. During the next half cycle, Q801 N-
MOS and Q802 P-MOS are OFF while Q801 P-MOS and Q802 N-MOS are ON. This
develops an alternating current through the transformer primary.
The result in T801 primary coil has an AC square waveform.
Certainly, the secondary of T801 will produce high voltage AC sinusoidal waveform.
