1 · This paper proposes a new DC-DC converter for auxiliary power applications with high input voltage. The proposed structure integrates switched capacitor cells with a forward converter. The input voltage is divided through the SC (switched-capacitor) cells, enabling switches rated for a lower voltage level. The proposed integration is performed …

Learn MoreIn 1978, a company in Osaka, Japan began to produce gold capacitors, which were the first carbon double-layer capacitors to be commercialized and mass-produced. In 1979, Nippon Electric (Nippon Electirc Company, Limited) used supercapacitors in the starting system of electric vehicles and began to produce …
Learn MoreWhen a feed-through capacitor is integrated into a circuit or system, it is connected in series with the signal or power line that requires noise suppression. The feed-through capacitor acts as a barrier to high-frequency noise, allowing the desired signals to pass through relatively unaffected.

Learn MoreAn integrating ADC is a type of analog-to-digital converter that converts an unknown input voltage into a digital representation through the use of an integrator. In its basic implementation, the dual-slope converter, the unknown input voltage is applied to the input of the integrator and allowed to ramp for a fixed time period (the run-up period). Then a known reference voltage of opposite polarity is applied to the integrator and is allowed to ramp until the integrator output returns to ze…
