    Abstract: A surge voltage generated by the switching operation of an IGBT element and voltage variation generated in an equivalent series resistance of a capacitor are superimposed on an input voltage of an inverter. The equivalent series resistance has a temperature dependence that a resistance value increases with a decrease in a capacitor temperature. The IGBT element has a temperature dependence that an element withstand voltage decreases with a decrease in an inverter temperature. When capacitor temperature is lower than a predetermined threshold value, a control device reduces an upper limit value of the input voltage by an amount corresponding to the voltage variation from its upper limit value at a high temperature, and controls a target voltage of a boost converter such that an output voltage does not exceed the upper limit value. Consequently, the allowable range of the surge voltage can be ensured.

    Abstract: A controller for a vehicle including at least one motor driving wheels, an inverter driving the motor, and a boosting converter supplying a dc power supply current to the inverter, is provided with a control portion performing rectangular wave control and non-rectangular wave control on the inverter in a switched manner. The control portion has an emergency switching condition for switching control from the rectangular wave control to the non-rectangular wave control, as a determination reference, and when the emergency switching condition is satisfied while the rectangular wave control is being executed (YES at step S5), the control portion instructs the boosting converter to lower target output voltage (S7). Preferably, the control portion determines that the emergency switching condition is satisfied when a q-axis current supplied from the inverter to the motor exceeds a prescribed threshold value.

    Abstract: In a motor drive control system configured to include a converter capable of stepping up the voltage, when the locked state of MG2 operating as an electric motor does not occur (NO in S130), a voltage command value VHref for the converter output voltage is set according to respective required voltages of MG1 operating as an electric generator and MG2 (S140). In contrast, when the locked state of MG2 occurs (YES in S130), the voltage command value VHref is set to a limit voltage Vlmt or less for limiting the voltage step-up by the converter (S150, S180). When the locked state occurs, the converter output voltage is decreased and accordingly the DC voltage switched by the inverter is lowered, so that a switching loss at the switching device forming a part of the inverter is reduced and the temperature increase due to the heat generation can be suppressed.
