摘要： A lighting driver includes a rectifier having an input connected to receive AC electrical power from an electronic ballast and having an output connected to supply a current to a plurality of light emitting diodes (LEDs) arranged in series with each other in a string, and a switching device disposed at the output of the rectifier and configured to receive a switching control signal and in response thereto to execute a switching operation to modulate an amount of power supplied to the plurality of LEDs so as to cause an average of the power supplied to the plurality of LEDs to be equal to a target power level. A current sensor may be provided to sense the current, and a controller configured to control the switching operation of the switching device in response to the sensed current.

摘要： For converting a first DC voltage to a second DC voltage, a first bridge circuit comprised in a power converter is controlled to convert the first DC voltage to a first AC voltage. The first AC voltage is transformed to a second and possibly further AC voltage. The second and each possibly further AC voltage is converted to a DC voltage by respective bridge circuits. To increase efficiency of the power converter switches of the power converter are controlled to operate in soft switching. Thereto a duty cycle of each AC voltage is controlled. In an embodiment, a half-cycle voltage-time integral of each AC voltage is controlled to be substantially equal.
