In this paper, a direct ac-dc power electronic converter topology is proposed for efficient and optimum energy harvesting from low-voltage microgenerators. The converter utilizes the bidirectional current-conduction capability of MOSFETs to avoid the use of a front-end bridge rectifier. It is operated in discontinuous conduction mode and offers a resistive load to the microgenerator. Detailed analysis...
In this paper, a step-up micro power converter for solar energy harvesting applications is presented. The circuit is based on a switched-capacitor voltage doubler architecture with MOSFET capacitors, which results in an area approximately eight times smaller than using MiM capacitors for the 0.13μm CMOS technology. In order to compensate for the loss of efficiency, due to the larger parasitic capacitances,...
In this paper a new current-mode true RMS-DC converter based on a two-quadrant squarer/divider is presented. The circuit employs MOSFETs that operate in strong inverted saturation region performing electronically simulated translinear loop. The converter features very low supply voltage (1.2 V), immune from body effect, two-quadrant input current, large dynamic range, and low circuit complexity. Simulation...
