Abstract
A phase detector which determines the phase based upon the output signals from a power coupler. The power coupler outputs a first signal and a second signal. The first and second signals are input to a magnitude detector which determines the magnitude of the relative phase between the first and second signals. The first and second signals are also input to a sign discriminator which determines the sign of the phase between the first and second signals.

A power delivery system receiving an input power and generating an output power to a load comprising:
- a power generator, the power generator receiving the input power and generating the output power, the power generator output being applied to the load;
- a directional coupler interposed between the load and the power generator for sensing a forward power and a reflected power;
- and
- a phase detector for determining a relative phase between the forward power and the reflected power.
An apparatus comprising:
- a power delivery system coupler receiving an output from a power generator for detecting a first parameter and a second parameter, the coupler generating a respective first signal and a second signal, each signal varying in accordance with the respective first and second parameters;
- and
- a phase detector, the phase detector receiving the first signal and the second signal form the coupler, the phase detector determining a relative phase between the first signal and the second signal in accordance with the first parameter and the second parameter.
A method for phase detection comprising the steps of:
- providing a power delivery system having a coupler receiving an output from a power generator;
- detecting a first parameter and a second parameter using the power coupler;
- generating a first signal and a second signal based upon respective first parameter and second parameter, each signal varying in accordance with the respective first and second parameters;
- and
- determining a relative phase between the first signal and the second signal in accordance with the first parameter and the second parameter.
