Abstract
Various embodiments include a half-bridge comprising: a first power semiconductor; a second power semiconductor connected in series with the first power conductor; a controller for the power semiconductors; a line starting at connection node of the power semiconductors; and a meter for measuring the current in the line. The controller is configured to: compare the current with an upper threshold value and a lower threshold value; switch off the first power semiconductor if the upper threshold value is reached; switch on the second power semiconductor after a first dead time has elapsed; and switch off the second power semiconductor if the lower threshold value is reached; and switch on the first power semiconductor after a second dead time has elapsed.
