Here is the Structural Dissociation 101 explanation:
Take a person. Something traumatic happens. Trauma is per definition overwhelming (if it not too much too handle, it is not traumatic). The individual copes by splitting off / insulating / isolating / separating the incident into a neat little package in the psyche so that the rest can get on with daily life. The person who gets on with daily life is called the ANP (Apparently Normal Personality), the split off part put on ice / the backburner / the vault is called the EP (Emotional Personality.) This works for a while, until flashbacks etc force the person to deal with and integrate the contents of the package, held by the EP, into the ANP. This is called Primary Dissociation - which is what 'pure' PTSD is about.
With complex trauma you don't have 'a person' - you have a being consisting of many traumatic incidents / memories. What happens is that the EP splits into two or more (many more) little EPs - and they are 'created' at different ages under different conditions and they start acting almost independently. This is Secondary Dissociation. Ir seems as if this is OSDD (in the DSM IV this was called DDNOS)
In cases of very severe childhood trauma, Tertiary Dissociation happens - this is where the ANP splits into separate, fully autonomous personalities - this is DID.
I hope this helps.
