Claim of US Patent No. 9,231,482

1. An apparatus for regulating an energy system which is connected to a DC voltage, comprising
a first capacitive voltage divider (7), arranged between a first terminal of the DC voltage and a reference potential, the first capacitive divider (7) comprising a first capacitance (71) and a second capacitance (72, 73) connected in series, and a first terminal of the first capacitance (71) is connected to the first terminal of the DC voltage, a second terminal of the first capacitance (71) is connected to a first terminal of the second capacitance (72, 73) in order to form the central terminal (A) of the first voltage divider (7), and a second terminal of the second capacitance (72, 73) is connected to the reference potential;

a first resistor (74), arranged in parallel with the second capacitance (72, 73);

a second capacitive voltage divider (8), arranged between a second terminal of the DC voltage and the reference potential, the second capacitive divider (8) comprising a third capacitance (81) and a fourth capacitance (82, 83) connected in series, and a first terminal of the third capacitance (81) is connected to the second terminal of the DC voltage, a second terminal of the third capacitance (81) is connected to a first terminal of the fourth capacitance (82, 83) in order to form the central terminal (B) of the second voltage divider (8), and a second terminal of the fourth capacitance (82, 83) is connected to the reference potential;

a second resistor (84) arranged in parallel with the fourth capacitance (82, 83);

a voltage detector (25), configured to detect a voltage difference between a central terminal (A) of the first voltage divider (7) and a central terminal (B) of the second voltage divider (8); and

a compensation apparatus (16), configured to control the energy system connected to the DC voltage based on the detected voltage difference.
