AMPLIFIER CIRCUIT

PROBLEM TO BE SOLVED: To solve problems that a maximum output that can be extracted is small in conventional single end amplification and odd-order distortion or zero-cross distortion easily occurs in push-pull amplification when using a vacuum tube as an amplification element, it is necessary to always pay attention to maintenance of operational balancing, it is required to consider to a maximum a pairing property of elements and the maintenance of operational balance in amplification by a vacuum tube SEPP that is configured of a plurality of elements or complementary push-pull amplification using a semiconductor element, and both positive and negative large-scaled power sources extremely excellent in regulation performance is needed. SOLUTION: Two winding wires of the same inductance capacitance are regarded as an equivalently single winding wire, and a hot side winding wire and a cold side winding wire thereof are swung with opposite phases only by a single electrode vacuum tube or a complementary single pair semiconductor elements. A large output beyond the conventional circuit is extracted to attain enhancement in various characteristics and to also ensure operational stability or reliability. COPYRIGHT: (C)2008,JPO&INPIT
