A Four-Quadrant Switched Capacitor DC-DC Convertor Enabling Power-Efficient Lab-Grade Potentiostats [PDF]
2020 IEEE 20th Mediterranean Electrotechnical Conference ( MELECON), 2020 This paper presents a low-power potentiostat based on a four-quadrant switched capacitor DC-DC convertor for use in lab applications. The gearbox convertor achieves a compliance voltage of ±2.5V. Through the use of frequency scaling, the convertor features output currents in the range of 1µA to 1mA, outclassing other state-of-the-art power efficient ...

The Topologies of Multi-Input Single-Output Isolation-Free DC-DC Convertor for Hybrid Power Plants
Balkan Journal of Electrical and Computer Engineering, 2021 Today it is an obvious fact that energy consumption tends to increase due to technological developments, population growth, and increasing living standards. In last two decades, renewable energy sources are accepted the most convenient way. However, most of these alternative systems are not considered sufficient to supply whole demand alone. But hybrid

Electrostatic Energy Harvesting Circuit with DC-DC Convertor for Vibration Power Generation System
Journal of Physics: Conference Series, 2016 This paper presents an interface circuit with power control features for electrostatic vibration energy harvesting. A DC-DC convertor is used to control the output voltage of a diode-based charge pump circuit. Therefore, the maximum and minimum voltage across the variable capacitor of the energy harvester may be adjusted to track the maximum power ...
