摘要： The voltage applied to a power converter is detected by a voltage detector, a function generator produces a voltage proportional to this detected voltage, and a high-pass filter detects an AC component superimposed on the voltage. An adder adds a bias voltage to this AC component, and an adder adds the output from the adder and the output from the function generator. The output from the adder is compared with a triangular wave produced from a rectangular wave generator, and a switching element is controlled to make switching operation according to the compared result. When a DC current is decreased by the AC component, a resistance current Ib is increased so that the AC components superimposed on the current and resistance current can be cancelled out.

摘要： Filter capacitor voltage “Ecf1” is detected and then after d-axis voltage correction value “dvd”, q-axis voltage correction value “dvq”, q-axis current correction value “diq”, and frequency correction value “d&ohgr;1” have been computed from the AC components of “Ecf1” and the results have been added to the corresponding d-axis voltage command, q-axis voltage command, q-axis current, and frequency command, the DC current of the power converter is controlled. Thus, the AC components included in the DC current are offset and the AC components are suppressed effectively.

摘要： An inverter device includes plural modules, each module being formed by a series circuit having a parallel circuit of a first switching device and a first diode, and a parallel circuit of a second switching device and a second diode, allowing a reduced size, high reliability, high frequency switching and low noise. Each module forms one arm portion of the inverter. Lifetimes of the diodes and the switching devices are set in a manner to equalize losses in the inverter. Preferably, insulated gate bipolar transistors (IGBTs) formed by diffusion are used as the switching devices since the lifetimes of these devices can easily be adjusted to optimize design of the inverter.

摘要： To determine the timing of the electrical brake for completely stopping in electrical braking control, and also to achieve both sure stopping and good riding comfort in an electric vehicle powered by the motor by decreasing the braking force at a prescribed rate of change, the torque of the electric motor is controlled by controlling the power converter which powers the motor using a power converter controller. The deceleration of the motor is computed based on the detected speed of the electric motor which is as an output of the speed detection means, the subsequent speed of the electric motor is estimated based on the detected speed and the deceleration rate of the electric motor at the time the detected rotational speed of the electric motor falls below a prescribed speed, and torque control is carried out using an electric power converter controller, based on the estimated speed.
