Abstract
A power converting apparatus is connected to a second power converting apparatus via a power supply line and an earth line, and includes: a carrier-signal generating unit configured to switch a frequency to a frequency selected from a plurality of candidate frequencies or a candidate frequency range according to information to be transmitted to the second power converting apparatus and generate a carrier signal having the switched frequency; a PWM-signal generating unit configured to generate a PWM signal using the generated carrier signal; and a switching element for controlling a control target, which makes switching according to the PWM signal to thereby perform an operation for power conversion and transmits a voltage-to-earth signal corresponding to the information to be transmitted, to the second power converting apparatus via the power supply line and the earth line.
