I was researching about inverters when I came across the Z source inverter. The Z source inverter is unique in a sense that it enables a shoot-through or a short circuit condition by closing any two switches of the same leg. This would not be possible in a traditional inverter as such a situation would cause the switches to get damaged. But a shoot-through state in a Z source inverter is possible due to the presence of the so called "LC" network. My question is this:
1) How does the LC network prevent any damage of the switch during the short circuit stage?(this is similar to a boost converter when the inductor charges during the 'on time' of the switch in a standard PWM. The closed switch and the inductor effectively creates a short circuit but there is no damage of the switch).
2) What is the use of connecting the capacitors in an "X" like fashion in between the inductors?
