A driving arrangement is provided for driving a load, comprising a driver input for receiving an input power and a driver output to be coupled to the load. A high frequency switch mode PFC converter converts the input power to a PFC converter power and a high frequency switch mode regulator has an output connected in series with the output of the PFC converter. A superimposed power from the PFC converter and the regulator with synchronized high frequency switching is provided to the load. This enables a high frequency ripple to be at least partially cancelled. Wherein the charging phase of the PFC converter at least partially overlaps with the first phase of the regulator in which phase the regulated power increases.

Driver for driving a load, such as a LED load

A driver circuit is for driving a GaN power commutation switch of a switch mode power converter. A sensing component is connected to the GaN switch for sensing a parameter such as a peak current of the power commutation. An energy storage component provides a certain turn on voltage between the gate and source of the GaN switch. The charging and discharging of the energy storage component is regulated, and the sensing is disabled with timing which is synchronized with the charging and discharging function of the energy storage component. It is prevented that a voltage across the sensing component reduces the generated gate-source drive voltage of the GaN switch.

A boost converter has a main energy storage inductor and a main GaN boost switch with a node between them. A pre-charging switch is connected at the output side of the main boost switch and the inductor, between the node and an output capacitor. The pre-charging switch comprises a body diode in the forward direction from the output capacitor to the node. The output capacitor is charged by the pre-charging switch in a pre-charge phase and this provides a soft start-up to avoid large inrush currents. A third switch, which is also a GaN switch, is in series with the pre-charging switch to provide synchronous output rectification. The third switch has a body diode in a forward direction from the node to the output capacitor. In the pre-charge phase, both the boost switch and third switch are turned off whereas in a subsequent boost phase, the pre-charging switch is turned constantly on, and alternately the boost switch and the third switch are turned on and off to implement the boost conversion.
