A switching circuit includes a high-side transistor and a low-side transistor, each of which is of an N-channel type. A switch and a rectifying element of a PMOS transistor are provided in series between a constant voltage line through which a constant voltage is supplied and a bootstrap line. A comparison circuit operates using a high-side power supply voltage, which is a potential difference between the bootstrap line and a switching line, as a power supply to generate a detection signal indicating a magnitude relationship between the high-side power supply voltage and a threshold voltage. A level shift circuit level-shifts the detection signal down to a signal of which a ground voltage is low. A PMOS driver drives the switch asynchronously with switching of the low-side transistor in response to an output of the level shift circuit.

Techniques are disclosed that use an alternating current bridge circuit to determine whether an impedance change occurs at an input to DC-DC voltage converter(s).

In a system for feeding a DC link and a method for operating the system, a sensor for detecting a current in the DC link or voltage on the DC link is connected to a controller, which activates a second converter, e.g., a DC/DC converter or current controller. A first energy storage device is connected via the second converter to the DC link, and the controller activates a third converter, e.g., a DC/DC converter or current controller. A second energy storage device is connected via the third converter to the DC link, and the first and the second energy storage devices are different, e.g., have a different dynamic behavior and/or different discharge time constants.
