Low-Cost Drive Circuit For AC-Direct LED Lamps

Low-Cost Drive Circuit for AC-Direct LED Lamps Abstract This paper proposes a drive circuit for ac-direct LED lamps. The proposed circuit consists only of a line filter, an LED bridge, a load inductor, a bidirectional switch, and a switch-control circuit. The switch connects the LED bridge to the power line directly. Each leg of the […]


Auxiliary Circuits For Power Flow Control In Multi frequency Wireless Power Transfer Systems With Multiple Receivers

Auxiliary Circuits for Power Flow Control in Multifrequency Wireless Power Transfer Systems With Multiple Receivers Abstract This paper describes a technique for multifrequency wireless power transfer systems in which the wireless power can be transmitted through the wireless power transfer channel or channels from the transmitter to the targeted loads with receiver coils specifically tuned […]
