In this proposal, the energy harvesting (EH) interface for a high voltage triboelectric nanogenerator (TENG) is proposed using the 180 nm CMOS process. A controller is designed to detect the rectified voltage of the active bias flip rectifier (ABFR). The maximum power point tracking (MPPT) control is used to extract the maximum available power from the TENG. The rectified voltage is transferred to the battery/load through an inductor through the proposed Master-Slave buck-converter (MSB) operation. The zero current sensing (ZCS) controller eliminates the reverse current, and a capacitively coupled level shifter is used to control the high-side power switches. The simulated results show that the proposed EH interface circuit gives an output of 5.5V while the input source is 70V. |
