| 摘要 |
A switch control circuit ( 416, 402, 418, 422 ) and method are provided for transistor-implemented switches ( 405, 413, 408, 414 ) of an integrated floating power transfer device ( 400, 500 ). The device includes a floating bus ( 403, 410 ) driven by a power system which includes a charge pump circuit ( 419, 408, 414, 420 ). At least one switch circuit ( 405, 413 ) is coupled to the floating bus and the power system for facilitating charging of the floating bus. The switch control circuit ( 416, 402, 418, 422 ) includes a level shifting circuit ( 402 ) for adjusting a control signal to the at least one switch circuit notwithstanding floating of an input voltage signal thereto to facilitate operation of the switch circuit.
