Title:
POWER CONTROL CIRCUIT
Document Type and Number:
Japanese Patent JPH09230947
Kind Code:
A
Abstract:
To provide the control circuit which suppresses the generation of higher harmonics.
This circuit is equipped with a differential transformer which has 1st input terminals 1 and 2 and 2nd input terminals 5 and 6 and output terminals 9 and 10. A power source 4 which applies a specific voltage is connected to the 1st input terminals 1 and 2 and a power source 4 which is opposite in phase from the 1st input terminals 1 and 2 is connected to the 2nd input terminals 5 and 6, and a variable capacitor 8 is arranged between the power source 4 and 2nd input terminals 5 and 6.
