a & b Please

1. Given the following half-bridge inverter. D1 T VDC2 50V AS VAS VDC/2 50V Figure 1. Half Bridge Inverter a. Determine the switching scheme that will provide an AC output voltage VAS b. For the switching scheme in a. plot the voltage Vas, and the current ias assuming purely inductive load. Label the devices that conduct over the entire period. VAS -50V AS 60 120 180 240 300 360 Describe advantages and disadvantages of the circuit shown to the full H-Bridge inverter with 4 switches. c.
