Half bridge circuit, full bridge circuit constructed with half bridge circuit, and three-phase inverter circuit constructed with half bridge circuit

A half bridge circuit comprising:

• an upper arm;
• a lower arm;
• and
• a control circuit that controls the upper arm and the lower arm,
• wherein
• the upper arm includes a first switch element,
• the lower arm includes a second switch element,
• the first switch element and the second switch element are a semiconductor element including a first terminal that controls a current and a second terminal and a third terminal that input and output the current,
• when a voltage between the first terminal and the third terminal or a voltage between the first terminal and the second terminal is greater than or equal to a threshold voltage, the current is passed from the second terminal to the third terminal or from the third terminal to the second terminal in accordance with a polarity of the voltage between the second terminal and the third terminal,
• when the current is passed from the third terminal to the second terminal, the voltage between the second terminal and the third terminal changes with respect to the voltage applied between the first terminal and the third terminal within a range where the voltage between the first terminal and the third terminal is less than or equal to the threshold voltage,
• when the second switch element is turned off, the voltage between the first terminal and the third terminal of the second switch element is switched to a substantial zero voltage or a negative bias voltage, and
• before the first switch element is turned off, the voltage between the first terminal and the third terminal of the second switch element is switched from the negative bias voltage to the substantial zero voltage.
