  • Voltage supply
    Patent number: 8767412
    Abstract: Control devices can be destroyed or damaged by their supply voltage in the event of malfunction. The voltage supply according to the present invention comprises a means (12) having a primary part (121) and secondary part (122), the primary part (121) being connected to the voltage source (10) and being controllable by means of the voltage output (112) of the voltage converter (11), and the secondary part (122) comprising a first and a second mutually independent winding, a supply voltage for the control device being made available by means of the first winding, and the second winding being connected to the voltage input (111) of the voltage converter (11) so that a supply voltage, additional to the voltage source (10), for the voltage converter (11) is implemented by means of the second winding.

  • DC-DC converter circuit for converting an input voltage to an output voltage with a predetermined holdover time
    Patent number: 7015748
    Abstract: The DC-DC converter circuit has a converter unit for conversion of an input voltage to an output voltage; a first capacitor for maintaining a value of the output voltage for a predetermined holdover time; a charging circuit for charging the capacitor with a supply voltage that is greater than the input voltage and a discharging circuit for providing charge to the converter circuit from the charged capacitor when the input voltage is interrupted, whereby the output voltage is maintained for a predetermined holdover time.
