    • In controlling switching elements of a current source inverter, a switching loss in the switching element is prevented according to a normal switching operation for a commutation operation, without requiring any particular control.In the commutation operation of the current source inverter, a timing for driving the switching elements is controlled in such a manner that an overlap period is generated, during when both a switching element at the commutation source and a switching element at the commutation target are set to be the ON state, a resonant circuit is controlled based on the control of the switching elements having this overlap period, and resonant current of the resonant circuit reduces the switching loss upon commutation operation of the switching elements. By controlling the generation of the resonant current of the resonant circuit by using the control of the switching elements having the overlap period, the resonant current generated by this control renders current and voltage of the switching element at the commutation source to zero when commutation is performed, thereby reducing the switching loss in the commutation operation.

    • The present invention is directed to an apparatus for suppressing abnormal electrical discharge used for vacuum equipment which supplies power from a high-frequency power source to a plasma reaction chamber and executes a film formation process, provided with a power controller for controlling the high-frequency power source based on a deviation between a power command value and a power feedback value, and a cutoff controller for cutting off the power supply from the high-frequency power source to the plasma reaction chamber, based on a detection of the abnormal electrical discharge within the plasma reaction chamber. The cutoff controller exercises a first handling cutoff control and a second handling cutoff control, each having a different cutoff time. The first handling cutoff allows ions to remain in the plasma reaction chamber, and exercises the cutoff control over the high-frequency power source within a time duration which allows an arcing element to disappear. On the other hand, the second handling cutoff control exercises cutoff control over the high-frequency power source within a time range which allows abnormal arc ions to disappear. Accordingly, it is possible to supply power to plasma stably.
