Half Bridge¶
Power Switching Stage
Overview¶
The half bridge converts the low-power timing information generated by REVA into the external waveform delivered to the load.

Purpose¶
The half bridge allows:
- bipolar excitation,
- efficient switching,
- operation over a wide frequency range,
- isolation between control and power domains.

Role Inside REVA¶
The half bridge does not determine timing.
All timing originates inside Timer1.
The power stage merely reproduces the waveform established by the carrier engine.
