  • Capacitor charger system and digital control module and isolated acquisition module for such a capacitor charger system
    Patent number: 8797001
    Abstract: The invention relates to a capacitor charger system (100) comprising a capacitor charger module (110), an isolated acquisition module (120), and a digital control module (130). The isolated acquisition module (120) is configured for sampling an output voltage level of said capacitor charger module (110). The digital control module (130) is connected to the isolated acquisition module (120) via a bi-directional link and connected to the capacitor charger module (110) via a control signal interface. The digital control module (130) is configured for generating control signal information and synchronization signal information based on data representative of sampled output voltage levels received via the bi-directional link from the isolated acquisition module.
