Abstract: A capacitor charger system has a resonant power converter to connect to a capacitor via a rectifier. The resonant power converter has a switch-based bridge network, an internal transformer, a resonant circuit, and an amplitude stabilization circuit. The switch-based bridge network comprises at least one pair of switches. The resonant circuit includes a series-resonant branch with capacitive and inductive components, and the resonant circuit is connected in the circuit path to a midpoint between a pair of switches of the switch-based bridge network. The amplitude stabilization circuit provides stabilization of the resonant amplitude of the resonant circuit, and the amplitude stabilization circuit includes one-way conducting circuitry connected between an unrestricted node defined by a junction and a connection point of the resonant power converter having a predefined voltage level at operation. The resonant power converter connects to the output rectifier via the secondary winding of the internal transformer.

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.
