摘要： In a test of discharging a capacitor by electrically turning on a first switching element and a second switching element that are inserted in series in a conductor connecting a positive electrode and a negative electrode of the capacitor, a discharge current that passes through the first and second switching elements tend to apply stress on the first and second switching elements. In this discharge test, while a first control signal for putting the first switching element into a low resistance state is being applied to the first switching element, a second control signal increasing a voltage thereof over time is applied to the second switching element, and application of one of or both of the first and second control signals is stopped when a current detector detects a current. Since a discharge test ends when a limited discharge current starts flowing, stress associated with the discharge test is reduced.

摘要： A discharge controller carries out discharge control by determining a voltage to be applied to a conduction control terminal of each of switching elements such that a current in a non-saturation region of one of the switching elements is lower than a current in a non-saturation region of the other thereof, and applying the voltage to the conduction control terminal of each switching element with an opening-closing member opening an electrical path to turn on the switching elements, resulting in short-circuit of both electrodes of a capacitor so that a discharge current is outputted from the capacitor based on the discharge control. A manipulator manipulates, based on a value of the discharge current, how to apply the voltage to the conduction control terminal of the one of the switching elements, thus controlling an amount of heat to be generated in the one of the switching elements.

摘要： A motor control apparatus includes an inverter, a smoothing capacitor, power-converting drivers, a power-converting power supply circuit, and discharging drivers. The inverter includes switching circuits comprised of series-connected two IGBTs. The power-converting drivers apply an output voltage of the power-converting power supply circuit to the switching circuits to drive them, thus performing power conversion. The discharging drivers simultaneously turn on IGBTs of the switching circuit to discharge the smoothing capacitor when the output voltage of the power-converting power supply circuit is equal to or lower than a threshold. This prevents discharging of the smoothing capacitor during power converting operations.
