The Temporary High Power Circuit (THPC) consists of two parts:
Firstly, a power measurement circuit is implemented: The capacitor
charged with a constant current
and grounded the other time. Thus the average of the sawtooth voltage
proportional to the converter´s output power (at constant output voltages). The charge
current
