  • High-power transformer
    Patent number: 4829417
    Abstract: The secondary winding of a high power transformer for clocked power supplies is composed of a plurality of skeins extending parallel to one another which are, in turn, constructed of a plurality of stranded conductors extending parallel to one another, whereby the stranded conductors are composed of wire-shaped individual conductors respectively provided with an insulating surface and twisted or woven with one another. All stranded conductors are electrically and mechanically connected to one another at both ends of their respective skeins and all skeins are connected to one another at one end of the secondary winding and connected to one another across respective rectifiers at the other end thereof.

  • Control arrangement for a uniform load distribution of at least two power supply devices connected in parallel at the output side
    Patent number: 4383183
    Abstract: A control arrangement for the uniform load distribution of at least two power supply devices connected in parallel at their outputs and designed as switch controllers having pulse width modulators provides a common voltage regulator for the power supply devices and a respective non-steady and a steady current regulator per power supply device. The control outputs of three respective regulators are connectred to maximum value selection circuits which precede the pulse width modulators.

  • Circuit arrangement for limiting and regulating the collector current of the control element transistor of a switching network component
    Patent number: 4328537
    Abstract: An integrated regulating module for current and voltage regulation is employed in a circuit arrangement for limiting and regulating the collector current of a control transistor of a switching network component. The module comprises a pulse width modulator, a reference voltage source, an operational amplifier for current regulation, an operational amplifier for voltage regulation, a disconnect device and two dual outputs. The control transistor is connected in series with a current transformer whose secondary is connected in parallel to a series arrangement of a diode and a variable resistor, and a half-wave rectifier circuit. Two bistable switches are provided such that one input of the first bistable switch is connected to the reference voltage source of the regulating module and the other input is connected to the output of the regulating module.
