Abstract

PURPOSE:To perform matching accurately, by controlling the capacitance of a capacitor so that the phase difference between the voltage and the current is zero. CONSTITUTION:High frequency power from a high frequency oscillator 1 is applied to a load 3 via a matching means 2. A phase detecting circuit 4 which detects the phase difference of a current I0 to a voltage V0 controls the capacitance of a capacitor C1 so that the phase difference is zero. Further, in the matching means 2, a detector 5 detects a total conductance of a capacitor C2, coil L and load and controls the capacitance of the capacitor C2 so that this conductance is equal to the conductance of the oscillator. Thus, the matching between the oscillator and the load can be taken.
