Abstract: PROBLEM TO BE SOLVED: To obtain an inverter apparatus by which the life of an electrolytic capacitor is discriminated, so as to enhance its reliability. SOLUTION: An AC power supply 11 is input to an electronic power rectifier 13 via a breaker 12. The DC output of the electronic power rectifier 13 is input to an electronic power inverter 16 via a DC positive bus 14 and a DC negative bus 15. The AC output of the electronic power inverter 16 is supplied to a load 17. A parallel circuit which is composed of an electrolytic capacitor 18 and of a resistor 19 for discharge is connected to the DC positive bus 14 and the DC negative bus 15. A voltage across both the terminals of the electrolytic capacitor 18, which is detected by a voltage detection part 20, is supplied to a microcomputer 22.
