ABSTRACT:
A high frequency AC current-sourcing driving that can feed electrical loads with a constant current that is independent of load resistance. The driver is a self-oscillating inverter that includes a resonant network comprising a resonant capacitor and a resonant inductor. A current comparing and toggling circuit (CCTC) is used to generate the control signals of the inverter's power switches. Also included in the system is a DC blocking capacitor that prevents the DC voltage from reaching the resonant network.
