Half-bridge circuit arrangement and method for actuation

A method, for actuating a half-bridge circuit arrangement (1), comprising the steps of:

• providing said half-bridge circuit arrangement (1) having a first, upper circuit breaker (60), an actuation device (20) associated therewith and having a second, lower circuit breaker (62), an actuation device (22) associated therewith;
• wherein, a power input (602) of the upper circuit breaker (60) is connected to a first potential (80) of a DC voltage source, a power output (624) of the lower circuit breaker (62) is connected to a second potential (82) of a DC voltage source, and a center tap between the two circuit breakers (60, 62) is connected to an AC voltage output (84);
• wherein, after one of the two circuit breakers (60, 62) which is switched on as voltage generation switch for a first voltage generation period has been switched off, the other circuit breaker (60, 62), which is then operated as a measuring switch and is switched on for a measuring period;
• and
• switching said measuring switch on during said measuring period;
• determining the current, during the measuring period, by means of the measuring switch;
• and
• immediately, after the current has been determined, switching off the measuring switch and then the voltage generation switch is only switched on again for a second voltage generation period if no current has flowed via the measuring switch during the measuring period.
