Abstract
In each E-class inverter, an internal voltage detection circuit detects an internal voltage of a resonant type power supply circuit or a matching circuit and adjusts a phase of a driving signal of a MOSFET based on a detected voltage. It is thus possible to match a phase of a current voltage of a sine waveform of each inverter and combine power highly efficiently. Since power combining is performed highly efficiently without using a variable capacitor and variable inductor, it is possible to suppress upsizing of elements and achieve downsizing of a power amplifier circuit.
