Phase inversion

Phase inversion is the swapping of the two poles of an alternating current source. A phase inversion is neither a time shift nor a phase shift, but simply a swap of plus and minus.

For example, in a push-pull power amplifier using vacuum tubes, the signal is most often split by a phase splitter (aka phase inverter) stage which produces two signals, one in phase, and the other out of phase, that is, phase inverted. These two sinep signals then drive the two halves of the first push-pull stage, which may be either the output stage (in which case the phase splitter will be in between the driver stage if there is one and the output stage) or the driver stage. The other common arrangements for driving a push-pull stage are by using an isolation transformer to produce the split signals, or by using the in-phase half of the first push-pull stage to drive the other half. A common circuit using this last technique is the long-tailed pair, often seen in television sets and oscilloscopes.
