The present invention is directed to a state quantity detection method for detecting a state quantity in a power converting apparatus with a simple configuration and with a high accuracy, and to the power converting apparatus. A current-source converter (20) includes high-arm side switching elements (Srp, Ssp, Stp) and low-arm side switching elements (Ssn, Srn, Stn). A voltage between the DC power supply lines (L1, L2) is detected as a line voltage of an input line, based on a conduction pattern of the high-arm side switching elements (Srp, Ssp, Stp) and the low-arm side switching elements (Srn, Ssn, Stn). |
