  • Method for controlling a power factor correction circuit, power factor correction circuit and operating device for an illuminant
    Patent number: 10447146
    Abstract: For the purpose of power factor correction, an inductance (21) is supplied with an input voltage (Vin), wherein a controllable switching means (24) that is coupled to the inductance (21) is actuated in order to selectively charge and discharge the inductance (21). A control device (14) for actuating the switching means (24) is designed such that it actuates the switching means (24) selectively on the basis of one of a plurality of modes of operation. In a first mode of operation, a switch-on time is stipulated for the switching means (24) on the basis of a minimum waiting time and on the basis of a voltage that drops across the switching means (24).

  • Power factor correction circuit, operating device for a light-emitting means and method for controlling a power factor correction circuit
    Patent number: 9433060
    Abstract: A power factor correction circuit (11) comprises an input for receiving an input voltage (UIN), an inductance (21) coupled to the input, a switching means (24) that is coupled to the inductance (21) and that is controllable in order to either charge or discharge the inductance (21), and a control device (14). The control device (14) is set up in order to produce a control signal (Ctrl) for controlling the switching means (24) on the basis of a parameter value. The control device (14) is set up in order to ascertain the parameter value on the basis of an arithmetic sign of a time derivation for the input voltage (UIN).
