13.56 MHz RF Power Supply - EEVblog

eevblog.com/forum/projects/diy-metcal-13-56-mhz-rf-supply/?action=dlattach;attach=35846

L4 and L5. At power up pretty much all the RF energy is consumed by the tip cartridge. Once it reaches its design temperature, that RF energy is reflected back into the supply. This will lead to an increasing peak voltage seen by the peak-detector. In the end, the output of the OpAmp rises as well, causing a higher voltage at IC1's feedback input.

Diode detectors for RF measurement Part 1: Rectifier ...

g3ynh.info/circuits/Diode_det.pdf

The archetypical diode detector is the series half-wave rectifier, either driven by a transformer, or having an RF choke as a DC short-circuit across its input. This can be analysed on the basis that the choke or transformer is perfect, and results in the principal mathematical relationship that governs the detector's dynamic behaviour.
