SOLUTION: This controller is provided with an up/down counter part, a time delay part, and a sampling convertor part, and in each modulation region excluding one pulse modulation, this performs up-counting at operation of the inverter, and performs down-counting when the count value comes to a specified detection level or over, and also sets a switching frequency drop detection signal having a time delay of the time until the count value becoming zero, and lowers the switching frequency of the inverter to a specified value by this detection signal. At the same time, this returns the switching frequency to the initial value when this detection signal is cleared, using this detection signal as the trigger of the down count action of the counter part.

摘要： PROBLEM TO BE SOLVED: To eliminate timbre change of magnetic noise and control the whole range of an output voltage almost continuously, in a two-level inverter apparatus for an electric rolling stock. SOLUTION: A PWM means of an inverter is provided with a multi-pulse generating means 2 and a one-pulse generating means 3 of a one-pulse mode, which is independent of the means 2 which has a bipolar mode and an overmodulation mode interposed between the bipolar mode and the one-pulse mode, and controls asynchronously carrier waves and modulation waves in the means 3. The overmodulation mode outputs voltage pulses, in which the switching frequency changes continuously, and decreases gradually the switching frequency of the overmodulation mode, as the output frequency becomes higher. Thereby the timbre change which is present in the modulation system of the conventional inverter is eliminated, voltage can be controlled continuously when the multi-pulse mode transfers to the one-pulse mode, and fluctuation in the current and generation torque of a motor can be restrained.

摘要： PROBLEM TO BE SOLVED: To successively control the entire range of an output voltage by performing control with pulse width modulation until the modulation rate of a carrier amplitude reaches prescribed conditions and switching to the control of one-pulse mode when the prescribed conditions are reached for controlling a switching element. SOLUTION: A multiple pulse generation means 2, a one-pulse generation means 3, and a PWM mode selection means 4 generate the control signal of an inverter based on a phase θx of an output power fundamental wave that is found by integrating an output voltage command E* and a frequency command Fi* of an inverter by an integrator 1. An output voltage command→modulation rate conversion means finds a modulation rate A from the output voltage command E*. When a carrier amplitude width is set to 1, 0 1 result in a bipolar mode and overmodulation mode, respectively. A switching frequency becomes constant in the bipolar mode and gradually approaches the switching frequency in the overmodualtion mode, thus eliminating the discontinuous change in a magnetic noise and successively controlling an entire output voltage region.
