Industrial truck with a charger
First Claim
1. Industrial truck with a charger (10), an asynchronous machine (34) and an existing three-phase AC control unit (12) which converts a DC voltage of a battery (36) for the asynchronous machine (34), characterised in that the charger has a switching power supply (10) which is connected to the existing three-phase AC control unit (12) via a transformer (14), the switching power supply (10), the existing three-phase AC control unit (12) and the transformer (14) forming an integrated resonant converter, which converts a mains voltage into a charging voltage for the battery.
