The present invention discloses a highly reliable positive-to-negative voltage conversion circuit, including a first inverter, a first buffer, a second buffer, a first to seventh NMOS transistors, a first to third PMOS transistors, a first resistor, a second resistor, a third resistor, and a fourth resistor, wherein the third PMOS transistor, the third NMOS transistor, the fourth NMOS transistor, the fifth NMOS transistor, the sixth NMOS transistor and the seventh NMOS transistor form an on/off control circuit, with that a power supply path between a positive-voltage power supply terminal and a negative-voltage power supply terminal is physically isolated by the on/off control circuit to eliminate voltage reversing occurring when the positive-voltage power supply terminal and the negative-voltage power supply terminal cannot be synchronized during power-on.
