Space vector PWM signals
SVM provides means to derive the "voltage" which should appear at phaseA, phaseB, phaseC. HIGH == full +DC,  LOW = full -DC.

What is usually missing in such papers and descriptions is the final block - the commutation block. This block takes these phase signals and generates the required PWM for the upper and the lower switching device AND the deadtime during the transitions.

You are correct that essentially the actual drive signal are the compliment of each other WITH some interlock logic. 

Output = HIGH  => UpperSWT = ON,  LowerSWT = OFF

Output = LOW => UpperSWT = OFF,  LowerSWT = ON

Output = HIGH-LOW => UpperSWT = turnOFF,  LowerSWT = delayed TurnON

Output = LOW-HIGH => UpperSWT = delayed TurnON,  LowerSWT = turnOFF

Have a read of this paper I co-wrote. There is some PWM signals to the end
