Supply of power to primary conductors |
摘要 |
Apparatus for providing effective amounts of high-frequency AC power to a long primary trackway (1102), used for inductive power transfer includes transconductance-pi filters (1105) for deliberate mismatching; resulting in independence of current flow and track impedance. These cause the source (1101) to appear as a voltage source and the trackway to appear as a low reactance. Shorting the output (1106) cuts the connected trackway from power without harm. The filter can cause a voltage step-up so driving a longer track. Track termination apparatus is disclosed that acts as a short circuit at only the operating frequency while terminating the track at its characteristic impedance otherwise. Half-bridge and full-bridge power supplies (1101) are described for providing effective amounts of high-frequency AC power to a long primary trackway used for inductive power transfer.
