Abstract

1. Verstärkerschaltung für Elektromagnete von Proportio­ nal- oder Servoventilen.
2. Bei einer Verstärkerschaltung für Elektromagnete von Proportional- oder Servoventilen mit einer mittels eines Puls­ breiten-Modulators (2) einer Ansteuerschaltung angesteuer­ ten Transistor-Endstufe (4) ist letztere als eine Brücke ausge­ bildet, in deren vier Zweige je ein Power-MOS-Transistor (4) liegt und deren Diagonale den Ausgang für den Anschluß der Erregerwicklung (5) des Elektromagneten bildet. Die An­ steuerstufe weist eine Steuerlogik (8) auf, welche durch eine Steuerimpulsverzögerung die Brücke querstromfrei umschal­ tet. 1. Amplifier circuit for electromagnets of proportional or servo valves.
2. In an amplifier circuit for electromagnets of proportional or servo valves with a by means of a pulse-width modulator (2) a control circuit driven transistor output stage (4) the latter is formed as a bridge, in the four branches of which a power MOS -Transistor (4) and whose diagonal forms the output for the connection of the excitation winding (5) of the electromagnet. The control stage has a control logic (8) which switches the bridge without cross current by means of a control pulse delay.
