Abstract
To provide a power converter not to stop a DC power conversion of the power converter, when there is no abnormality in the main circuit of the power converter, and the command signal of output voltage has an abnormality. A power conversion circuit is provided with a voltage command upper limit circuit that upper-limits the voltage signal which is inputted to the switching control circuit by a preliminarily set upper limit voltage, wherein the voltage command upper limit circuit is provided with a Zener diode or a shunt regulator, wherein the Zener diode or the shunt regulator upper-limits the voltage signal by an upper limit voltage corresponding to Zener voltage or shunt voltage, and wherein a voltage command represented by the upper limit voltage is set to a voltage less than the protection determination voltage of the output overvoltage protection circuit.
