20110044074 | CONTROL ARRANGEMENT FOR A RESONANT MODE POWER CONVERTER - A resonant mode power converter is controlled with a control unit including a feedback circuit coupled to generate a first current representative of an output of the power converter. A current limiting circuit is coupled to receive the first current and a second current generated in response to a reference voltage. The current limiting circuit is coupled to limit the first current in response to the second current. An oscillator is coupled to receive the first current to generate a control signal having a control frequency in response to the first current. An output voltage of the power converter is controlled in response to the control frequency of the control signal. | 02-24-2011 |

20080198638 | CONTROL ARRANGEMENT FOR A RESONANT MODE POWER CONVERTER - The switching frequency of an LLC converter is controlled by a control unit to which a feedback circuit provides a first current dependent upon the output voltage of the converter. An oscillator circuit produces a sawtooth waveform at a frequency dependent upon the first current, up to a limit equal to a second current set by a resistor. Two complementary switch control signals are produced for controlling two switches of the converter for conduction in alternate cycles of the sawtooth waveform. A timer produces dead times between the two complementary switch control signals in dependence upon the second current. Another resistor provides a current constituting a minimum value of the first current, and a charging current of a capacitor in series with a resistor modifies the first current for soft starting of the converter. | 08-21-2008 |

20090316454 | POWER FACTOR CORRECTION CONVERTER CONTROL OFFSET - Power factor correction converter control offset apparatus and methods are disclosed. In one aspect, an apparatus includes a control unit to generate a control signal to control a duty cycle of a PWM (Pulse Width Modulation) switching signal that controls a switch in a PFC (Power Factor Correction) converter. An offset unit is also included and is coupled to the control unit, to generate a variable offset signal to offset the control signal or a signal used by the control unit to generate the control signal. | 12-24-2009 |
20120091982 | POWER FACTOR CORRECTION CONVERTER CONTROL OFFSET - An apparatus includes a control unit to generate a control signal to control a duty cycle of a PWM switching signal that controls a switch in a PFC converter. The control unit includes a PWM converter to produce a PWM signal responsive to an output voltage of the PFC converter. A switching circuit switches a current representing an input current of the PFC converter in response to the PWM signal. A circuit generates the control signal in response to the switched current.
