Low-inductance Ayrton-Perry Winding. Maximum continuous voltage is reduced to 70% of Series HS maximum voltage. Ayrton-Perry winding consists of two wires wound from opposite ends, and, therefore, connected in parallel, thus reducing maximum ohmic values obtainable.
Hence, inductance is also reduced considerably since the currents flow in opposite directions.
