If an emergency stop procedure results in all four switches being turned-off, describe what happens to the energy in the load including a description of the path load current would form in the inverter once all the switches are off. Assume the load is inductive (10mH) and is carrying 10A of current, and the dc link is 200V with a total dc link capacitance of 1mF, at the instant the procedure disables the switches.
e) In the circumstances of part d) calculate the rise in the dc link voltage that would occur.
