Malcolm,

I was speaking of the idealized case where a simple rectifier capacitor 
DC supply might be considered.  If one matches the impedance of the 
source (Top of the TC) to the capacitaive load, one will get maximum 
power transfer.  But if the load is of far greater impedance than the 
impedance of the supply, a much higher voltage might be realized than 
with best power transfer scenarios.
