DC-DC Converter and Rectifier with Resonator for Solar and Wireless Charging in Advanced Driver Assistance Systems

This paper designs a DC-DC converter and rectifier with resonator for wireless power transfer module (WPTM) and solar charging with ambient light sensor (ALS) in advanced driver assistance system when vehicles moving. The proposed boost DC-DC power converter serving as DC-to-AC converter with an embedded DC rectifier to provide the first-stage DC-DC converter, and charge pump support AC-to-DC converter with an input from the DC rectifier. Two differential, cross-coupled rectifiers as the charge pump circuit mitigate the reverse-leakage issue and they are cascaded to double the output voltage. The resonator uses the coil in multi-mode to drive wireless charging functions for power receiving unit (PRU) at parking slot and traffic stop. The proposed ambient light sensor can assistance solar charging direction to control motor of solar panel. The proposed solar charging with ambient light sensor that is direction to control motor of solar panel in advanced driver assistance system (ADAS).
