The invention relates to a half-bridge module which is arranged in an electrically insulating cooling liquid and in which two semiconductor switches form a half-bridge; the first semiconductor switch is capable of being connected by its source terminal to a high voltage potential, and the second semiconductor switch is capable of being connected by its drain terminal to a low voltage potential; the drain terminal of each first semiconductor switch is connected to the source terminal of the respective second semiconductor switch; whereby respective first semiconductor switches are arranged with their source terminal on a common first metallic conductor rail which is capable of being connected to the high voltage potential; respective second semiconductor switches are arranged with their source terminal on a second metallic conductor rail constituting the output which is arranged alongside the first conductor rail, spaced therefrom; each second semiconductor switch is connected by its drain terminal to a common third metallic conductor rail which is capable of being connected to the low voltage potential and is arranged alongside the first and second conductor rails, spaced therefrom; a capacitor arrangement having a backup capacitor which is connected to the first and third conductor rails and which overlaps the first and second semiconductor switches in such a manner that the semiconductor switches are spatially located between the corresponding conductor rails and the backup capacitor; a control input having a terminal for connection to the triggering device in the region of a first front side of the conductor rails, and the output having a terminal in the region of a second front side of the second conductor rail. |
