A power converter includes a control circuit provided with a set signal generator, a current command generator, a reset signal generator, a drive signal generator, and a pulse-width limiter. The set signal generator generates a set signal at every predetermined cycle. The current command generator generates a current command based on an output voltage command and an output voltage. The reset signal generator generates a reset signal based on an input current and the generated current command. The drive signal generator generates a drive signal which turns on in synchronisation with the generated set signal to turn on a switching element and which turns off in synchronization with the subsequently generated reset signal to turn off the switching element. The pulse-width limiter limits a pulse-width of the drive signal according to an input voltage and the output voltage, or according to the input voltage and the output voltage command.
