Hi Phil and all,
Regarding residual charge on the caps in the Equidrive circuit, the
assumption is that the current flowing through both caps is always
identical so there should be no differential charging between caps.
However, suppose there are pulsed corona discharges, or corona
rectification occurring between the secondary and the "floating"
primary. The additional current injected into the primary will cause
the floating potential of the primary to shift upwards or downwards,
thereby leading to offset voltages being developed (and stored)
across the caps once power is removed.
