PROBLEM TO BE SOLVED: To provide a high-voltage inverter having a high-voltage gate driving integrated circuit with low manufacturing cost.SOLUTION: An inverter 100 includes gate driving units 110, 120 and 130, an inverter unit 140, and bootstrap units 150, 160, and 170. The gate driving units 110, 120, and 130 have the same configurations; for example, the gate driving unit 110 includes high-voltage gate driving units 111 and 112, a high-voltage gate driver 113, and a low-voltage gate driver 114. The bootstrap units 150, 160, and 170 divide the voltage generated at the time of switching a plurality of switches of the inverter unit 140 according to the switching control of the gate driving units 110, 120, and 130; for example, the bootstrap units 150, 160, and 170 equally divide a voltage level of the power applied to a plurality of high-voltage gate drivers 111-1, 111-2, 112-1, and 112-2 of the gate driving unit 110. |
