Title:
電圧または電流を送出するスイッチング装置のための電圧供給装置および電圧または電流を送出するスイッチング装置のための電圧供給方法
Document Type and Number:
Japanese Patent JP2010541523
Kind Code:
A
Abstract:
A power supply for a voltage or current-releasing switching device having at least one coil for one of a voltage and current release includes a device which activates a switch means in a pulse-width modulated manner, the device configured for setting the current flowing in the coil, wherein inductance of the coil functions as an impedor of a clocked power supply which, via a rectifier diode and a storage capacitor, provides a first supply voltage that is predefinable via a comparison value. A voltage regulation device provides at least one second supply voltage. A measurement-resistor-free regulation device is provided for setting the current through the coil.
