摘要 |
A converter designed to be powered by a constant current and variable voltage source such as a coaxial cable of variable length includes regulation circuitry to regulate the input voltage of the converter. In particular, the switching device of a single-ended converter is pulse width modulated to regulate the input impedance and hence the input voltage of the converter to permit its efficient operation at varying cable lengths. |
