1. A voltage converting device comprising:
- an electric load having an electric power generating function;
a capacitor connected to an input of said electric load;
a down-converter down-converting a voltage of said capacitor;
first control means controlling an amount of electric power generated by said electric load; and
second control means outputting to said first control means a command for instructing prohibition of electric power generation in said electric load or for instructing decrease in an amount of electric power generated by said electric load, when said down-converter fails.

Abstract
A control device detects whether or not an up-converter fails, based on a DC voltage from a voltage sensor, an output voltage from a voltage sensor, and a duty ratio in controlling switching of NPN transistors. If a failure in the up-converter is detected, the control device then controls an inverter and an AC motor such that regenerative electric power generation in the AC motor is prohibited.
