Integrated High-Voltage Capacitive-Isolated AC-DC Power Conversion
Research Report Highlight
TxACE researchers at UTD report on the design of an integrated capacitive power transfer system with galvanic isolation. A peak efficiency of 50.7% has been achieved with maximum output power of 62 mW.
This report presents the circuit design and operation of the integrated capacitive power transfer (ICPT) system. The power converter is designed for the applications in industrial/automobile environments. The power stage is resilient to ground voltage surge and noise by using capacitive galvanic isolator, which can be fully integrated on silicon. At the same time, by using proposed operation scheme, this design can achieve a peak efficiency of 50.7% and the maximum output power of 62mW.
