Abstract

A switching module (1) is described. The switching module (1) comprises an H-bridge circuit (2) with four switching assemblies, and an active clamp circuit (6) with four controllable semiconductor switches (S5, S6, ..., S8). Each switching assembly comprises a pair of controllable semiconductor switches electrically connected an anti-series (S1, S2, ..., S4 and S9, S10, ..., S12). Alternatively, each switching assembly may comprise a controllable semiconductor switch and a diode electrically connected in series. The H-bridge circuit (2) comprises first and second AC bridge terminals (AC1, AC2) electrically connectable to a respective coil (4), and first and second DC bridge terminals (DC1, DC2) electrically connectable to a DC current source or to a DC bridge terminal of another switching module. The active clamp circuit (6) comprises first and second DC clamp terminals (DC3, DC4) between which an energy storage device (C) is electrically connected. A plurality of switching modules may be electrically connected together to provide a power electronic switching assembly.
