Patent number: 9007730Abstract: A surge protection circuit for a circuit having a rectification module. The surge protection circuit includes a first diode, a second diode, a capacitor and a discharge device. The anode of the first diode is connected to a first input of the rectification module, and the anode of the second diode is connected to a second input of the rectification module. The cathodes of the first and second diodes are both connected to the first plate of the capacitor. The second plate of the capacitor is connected to the negative output of the rectification module. The capacitor is configured such that it is consistently charged to substantially the peak value of a supply voltage during normal operation between surge events.Type: GrantFiled: December 29, 2010Date of Patent: April 14, 2015Assignee: NXP B.V.Inventors: Markus Schmid, Johann Baptist Daniel Kuebrich, Thomas Antonius Duerbaum, Gian Hoogzaad, Peter Laro, Frans Pansier

Patent number: 8692480Abstract: A power supply unit is provided which comprises an AC/DC conversion unit with an input to which an input voltage is coupled and an output to which a DC bus voltage is coupled. The power supply unit furthermore comprises a DC bus capacitor which is coupled to the output of the AC/DC conversion unit. The power supply unit furthermore comprises at least one sub-power supply unit receiving the DC bus voltage as input for providing at least one power supply. The power supply of the at least one sub-power supply unit or part of the load is at least reduced or switched off if the input voltage falls below a predetermined threshold value.Type: GrantFiled: September 4, 2009Date of Patent: April 8, 2014Assignee: NXP B.V.Inventors: Markus Schmid, Thomas Antonius Duerbaum, Gian Hoogzaad, Peter Laro, Johann Baptist Daniel Kuebrich

Patent number: 8441237Abstract: Consistent with an example embodiment, a circuit comprises a power factor correction stage having a DC input, a ground input, a DC output and a ground output. The circuit further includes a capacitor; a diode; and a discharge circuit. A first terminal of the diode is connected to an input of the power factor correction stage, a second terminal of the diode is connected to the first plate of the capacitor; and the second plate of the capacitor is connected to the other input of the PFC stage. The discharge circuit is connected to the capacitor and is configured to discharge the capacitor such that it contributes to the output of the PFC stage when the level of a signal at the input of the PFC stage falls below a threshold value.Type: GrantFiled: December 29, 2010Date of Patent: May 14, 2013Assignee: NXP B.V.Inventors: Markus Schmid, Johann Baptist Daniel Kuebrich, Thomas Antonius Duerbaum, Gian Hoogzaad, Peter Laro, Frans Pansier
