Abstract: This article proposes a condition monitoring method for the dc-link capacitor in railway traction converter systems with an LC resonant circuit. This method applies to nighttime routine ...

To address this issue, low power rating clamping circuits are implemented between each adjacent submodule of the MMC, and the capacitor charge differences caused by the PSC-PWM are analyzed.

Passive Components All the valves (tubes) in the circuit have cathode bypass, capacitors. Feedback obsessives might object to this, but this is current feedback not voltage negative feedback (NFB). We ...
