1. A controller of power supplying apparatus for controlling a power supplying apparatus which supplies power to a load by having switching elements connected in series with the power supply alternately perform switching operations comprising:

  • command means for outputting a timing signal, when said switching means are to perform the switching operations, to command the switching operations to be started;

    short-circuit prevention means for outputting, upon outputting of the timing signal from said command means, a short-circuit preventing signal until a preset short-circuit preventing period of time elapses; and

    control means for bringing, upon outputting of the timing signal from said command means, one of said switching elements which is in the conductive state into the non-conductive state and, in the meantime, bringing the other switching element which is in the non-conductive state into an intermittently conductive state until said short-circuit prevention means stops the outputting of the short-circuit preventing signal and, thereafter, holding the switching element in the conductive state.
