    The isotera system is a LED lighting system, whereby the electricity supply is a 50KHz sinusoidal current source. (1.9A average).
    Individual LED lamps are lit by a current transformer which "clips" over the 50KHz power bus and couples current to the LED lamp from the 50KHz power bus (and rectifies it)

    To get the 50Khz power bus, 50Hz mains is put into a "power hub", and this produces the 50KHz current.

    What if the voltage and current in the 50KHz power bus are not in phase with each other?
    .....if they are not in phase, then what does that mean for the "power hub" which produces the 50KHz sinusoidal current?
