  • Power supply circuit with scalable performance and method for operating the power supply circuit
    Patent number: 8410766
    Abstract: A power supply circuit and a method for operating the power supply circuit are described. In one embodiment, a power supply circuit includes multiple power elements configured to convert an input voltage to an output voltage, a driver circuit coupled to the power elements and configured to drive the power elements, a regulator controller coupled to the power elements and configured to control the power elements for the conversion of the input voltage to the output voltage, and at least one bypass switch coupled to the power elements. The at least one bypass switch is used to bypass at least one of the power elements. Other embodiments are also described.

  • Circuit arrangement for gaining a direct voltage using full bridge rectifier and coupling capacitors
    Patent number: 6678179
    Abstract: In the circuit arrangement according to the invention, means (1) for generating an alternating voltage from the DC input voltage are provided for gaining an offset-compensated DC output voltage from a DC input voltage, without using transformers and inductances. The alternating voltage is applied to at least one rectifier stage (2) which comprises two coupling capacitors (8, 9) and a subsequent full-bridge rectifier (10, 11, 12, 13) at its input, and is coupled at its output to an output capacitance (3) via which the DC output voltage decreases.

  • Fault tolerant air bag bus system without transformer
    Patent number: 6512308
    Abstract: A fault tolerant air bag system needs a floating supply, which supply conventionally is made by means of a DC-DC converter with a transformer. By splitting the main energy reserve capacitor (14) into two capacitors (14, 34), and coupling one of the capacitors (34) to the other (14) by means of switches (36, 38) which open during a crash, no transformer is needed any more.
