Inverter circuit and x-ray radiation device

An inverter circuit comprising:

• a plurality of semiconductor switching elements constituting a bridge circuit;
• a transformer connected to an output end of the bridge circuit;
• an electric current detector configured to detect whether an electric current carried through at least one of the plurality of semiconductor switching elements exceeds a predetermined value;
• a pulse generator circuit configured to transmit a periodic pulse signal;
• a flip-flop circuit connected to the electric current detector and the pulse generator circuit, the flip-flop circuit being configured to invert an output signal by a detection signal of the electric current detector to interrupt an output of the bridge circuit;
• an electric current bypass switch in which a signal from an output terminal of the flip-flop circuit controls turning on or off the electric current bypass switch;
• and
• a gate signal generator circuit connected to the electric current bypass switch and the bridge circuit, the gate signal generator circuit being configured to switch the semiconductor switching element at a diagonal position of the bridge circuit based on a signal from the pulse generator circuit.
