When an open phase occurs, there is a danger that the inverter could produce one of the following states;
(1) Ripple current of main capacitor increases, life of main capacitor shortens remarkably.
(2) In case of load, there is danger that the capacitors or thyristors inside the inverter could be damaged.
(3) There is a risk that the in-rush resistor to limit the current inside the inverter may burn out.
