A conversion apparatus including a plurality of high-speed switching devices, each being operable in latch type operation and non-latch type operation and a power source for supplying a first current to the high-speed switching devices, thereby forming a current path of the high-speed switching devices. The high-speed switching device is turned off after changeover from the latch type operation to the non-latch type operation. The conversion apparatus further includes a current regulation circuit provided in the current path for regulating a second current flowing through the current regulation circuit from a time when the second current reaches a prescribed value. In a case of overcurrent malfunction, the high-speed switching device is changed from the latch type operation to the non-latch type operation, and then is caused to be turned off during when the current regulation circuit regulates the second current.
