AB  - The self-compensated output transformer presented at the AES Convention held in Barcelona in May 2005, intended for Single ended audio amplifiers, is based on the principle that an auxiliary winding (named tertiary), crossed by the same current as the primary winding, can oppose a magnetic flux that reduces the overall flux, producd by the direct current, in the core, to almost zero. However, at the same time, this antagonist winding opposes also to the induced alternating current. A capacitor is therefore connected to its terminals, short-circuiting the alternating current. Under these circumstances, the alternating potential difference is close to zero and the primary is no less affected. But the above short-circuit has a drawback: it reduces the inductance of the primary, considerably.
