Effective Low Voltage to Medium Voltage Transmission on PRIME Band |
摘要 |
Coupling and interface circuits for powerline modems are disclosed. A powerline modem may be coupled to a low voltage (LV) line or a medium voltage (MV) line using a circuit that is designed to compensate for signal attenuation and loss that is created by the a LV/MV transformer and/or a MV coupler. In one embodiment, separate coupling transformers may be used by the modem for reception and transmission. In other embodiments, a capacitance is switched on the transmission line before the modem transmits to lower the line impedance.
