a) Using the H-bridge circuit, shown in Figure 1, in the inverting mode, it is possible to generate three different instantaneous voltage values for, Vab, (the load voltage). Assuming that the current is flowing in the load in the direction shown, Ia, list which switch pairs need to be turned on in order to generate each of the three possible voltage values. Voc Sta Sza A S16 S26 Figure 1 B b) What type of converter is the H-bridge from the point of view of the transformation ratio Vac Vab (buck, boost or buck-boost) assuming a current source is connected between the mid-points of the two phase legs and supplies a constant current Ia in the direction shown in Figure 1?
