Abstract
A device connectable to a three-phase network, wherein the device includes a capacitor, a secondary coil, a diode and, per phase, a conductor and a circuit, where a secondary-side coil is connected in parallel to the capacitor via the diode, the circuit is configured such that a resistor is located in a conductor, a first capacitor is connected parallel to the resistor, a serial circuit of a first primary-side coil is connected in parallel to the first capacitor, energy transfer occurs from a first primary-side coil to a second primary-side coil and to the secondary-side coil, a second capacitor is connected in parallel to the second primary-side coil, the second capacitor is connected to the source connection of a self-conducting field effect transistor, and the gate connection of the self-conducting field effect transistor is connected to the second capacitor to provide an improved internal power supply for the device.
