La potenza del dispositivo, ovvero la potenza di output dell'inverter, può essere espressa come: Pout=Ul2 / Ron (2)
Ul -------- tensione su entrambi i lati del sensore
Ron ------- impedenza equivalente del circuito risonante
It can be seen from the formula that there are two methods to regulate the output power of equipment, namely, voltage regulation and resistance regulation. Since the parallel resonant tank has the highest impedance during resonance, the power factor of the equipment reaches the maximum, which is what we expect. As a result, the voltage regulation is the optimal method, which can not only maintain the equipment at high Fattore di potenza, ma regola anche la potenza di uscita dell'apparecchiatura .
