Inductive power transfer across an extended gap

摘要: Inductive power transfer across an extended gap (100) from a primary conductor (119) is provided by means of resonant intermediate loop comprised capacitor (118) with inductor (117) - perhaps simply non-coiled wire carrying larger resonating current, that can in turn generate inductive field to be collected pickup coil (120). This may increase the rate or reduce alignment accuracy required IPT system, useful for vehicles as well lighting and display purposes, also offers frequency-stabilising features. An electroluminescent advertising panel powered sine-wave oscillator at 1.2 kHz; its DC 50 volts controlled secondary tuned system frequency 15 kHz placed near coil; which driven coupling fed alternating current frequency.
