Abstract
The invention relates to a method (300) for external monitoring of power electronics (450), wherein the power electronics (450) are actuated by means of first control electronics (460) and the method (300) is carried out by independent, second control electronics (420). The method comprises the following steps: determining (320) a parameter (P); determining (330) the difference (D) of between the determined parameter (P) and a target value (S); actuating (340) the power electronics (450) if the amount of the difference (D) exceeds a threshold (G).

A method (300) for external monitoring of power electronics (450), wherein the power electronics (450) are actuated by a first control electronics (460) and the method (300) is carried out by independent, second control electronics (420), having the steps of:
- determining (320) a parameter (P);
- determining (330) the difference (D) between the determined parameter (P) and a target value (S);
- actuating (340) the power electronics (450) if the amount of the difference (D) exceeds a threshold (G);
- wherein the step of actuation (340) of the power electronics (450) comprises a specification (342) of a control requirement (A) value for the first control electronics (460).
A system for external monitoring of power electronics (450), wherein the power electronics (450) are actuated by a first control electronics (460), wherein the system comprises an independent second control electronics (420) configured to:
- determine (320) a parameter (P);
- determine (330) the difference (D) between the determined parameter (P) and a target value (S);
- actuate (340) the power electronics (450) if the amount of the difference (D) exceeds a threshold (G);
- wherein the actuation of the power electronics (450) comprises a specification (342) of a control requirement (A) value for the first control electronics (460).
A device (400) for external monitoring of power electronics (450), wherein the power electronics (450) are actuated by a first control electronics (460), wherein the device (400) comprises an independent second control electronics (420) that are configured to determine a parameter (P), a difference (D) between the determined parameter (P) and a target value (S), and to actuate the power electronics (450) if the magnitude of the difference (D) exceeds a threshold value (G) wherein actuating the power electronics (450) comprises a specification (342) of a control requirement (A) value for the first control electronics (460).
