WebDefinition: Choke filter consists of an inductor connected in series with rectifier output circuit and a capacitor connected in parallel with the load resistor. It is also called L-section filter because the inductor and capacitor are connected in the shape of inverted L. The output pulsating DC voltage from a rectifier circuit passes through the inductor or choke coil. WebDC-BUS is technology for reliable and economical communication over noisy DC or AC power lines. The DC-BUS was originally developed by Yamar Electronics Ltd. together with the DC-BUS Alliance, for low cost sub-networks in vehicles, using the battery lines for in-vehicle data communication. The DC-BUS converts the digital input data into phase …
