Electronic circuit with two voltage supply circuits

An electronic circuit comprising:

• an output, which is configured to be connected to a load;
• and
• a first supply circuit and a second supply circuit, which are each connected to the output, and each comprise:
• a supply input, which is configured to receive a respective input voltage;
• a first circuit node;
• a first electronic switch, which is connected between the output and the first circuit node;
• a first rectifier element connected in parallel with the first electronic switch;
• at least one second electronic switch, which is connected between the supply input and the first circuit node;
• at least one second rectifier element, which is connected in parallel with the at least one second electronic switch, wherein the at least one second rectifier element and the first rectifier element are connected in antiseries with one another;
• and
• a control circuit, which is configured:
• to activate the first electronic switch and the second electronic switch and
• to receive a supply voltage from the first circuit node at a supply input,
• wherein at least one of the first and second supply circuits further comprises a current measurement arrangement configured to detect at least one current direction of an output current of the respective supply circuit.
