Abstract (en)
[origin: WO2021259758A1] The invention relates to a power output stage (10) for a device (1) for supplying energy to an electrical load (3), having a power switching device (12) which comprises at least one half-bridge (12.1) and is designed on the basis of gallium-nitride-on-silicon technology, and a control circuit (15) for the power switching device (12), wherein semiconductor power switches of the at least one half-bridge (12. 1) are formed as gallium-nitride semiconductors on a front face of a carrier substrate; the invention also relates to a device (1) for supplying energy to an electrical load (3), which device comprises such a power output stage (10), and to a method for determining a voltage-free switching time point for such a power output stage (10). The control circuit (15) comprises an auxiliary resonant commutated pole (ARCP) module (16B) each for the at least one half-bridge (12.1), which ARCP module has two auxiliary switches and a choke coil and is designed to switch the semiconductor power switches of the corresponding half-bridge (12.1) at a voltage-free switching time point, the control circuit (15) being designed to determine the voltage-free switching time point by means of integrated power measurement and/or by means of an adaptive delay chain.
