Claim 30:
31. A non-transitory machine readable media, storing machine interpretable instructions, which when executed, cause a processor to perform a method comprising:
generating a control command to control one or more states of one or more switches within:
two or more voltage source modules (VSMs);
a current source module (CSM) having one or more inductors, and having two or more switches, the two or more voltage source modules (VSMs) and the current source module (CSM) connected as a series connected string, the series connected string coupled to a higher-voltage DC network;
wherein two AC side terminals of the CSM are connected in series with two or more VSMs; and
two or three DC side terminals of the CSM are coupled to a lower-voltage network; and
wherein a current into the series connected string is equal to a current in one of the one or more inductors of the CSM for a first portion of each period and equal to a negative of the current in an inductor of the one or more inductors of the CSM for a second portion of each period.
