摘要： PROBLEM TO BE SOLVED: To obtain a vehicle power converter which can remove AC ripple frequency components, superposed upon an output of a pulse generator which detects the revolution of a wheel, and can utilize only the fundamental wave component as the motor frequency.
SOLUTION: The output of a pulse generator 1 which detects a revolution of a wheel is inputted to a filter 12. After the phase of the output of the filter 12 is converted into an opposite phase by a phase converter 13, the output of the filter 12 is made to pass through a motor frequency converter 5, the output of the pulse generator 1 is added to the output of the motor frequency converter 5 to remove AC ripple frequency components superposed upon the output of the pulse generator 1, and a motor frequency is obtained. The sum of the motor frequency and a slip frequency pattern is inputted to a PWM inverter controller 9, to control a voltage-type PWM inverter 10.

摘要： PROBLEM TO BE SOLVED: To control acceleration of an electric bicycle and prevent run away due to a miss-operation of an accelerator. SOLUTION: In an electric bicycle having a motor 33 driven by a battery 43 and a speed controller 73, the speed controller comprises a brake switch 53 outputting a signal in correspond to an operation of a rear brake, a vehicle rotation sensor 51 outputting a pulse in proportion to a rotational speed of rear wheels, and a control circuit 75. The control circuit 75 calculates changes of intervals of the pulse signals coming from the wheel rotation sensor to get an acceleration value, remembers the value, and supply a driving current to the motor corresponding to the remembered acceleration value. The remembered acceleration value is revised when it is calculated that the value is exceeded and the value is eliminated when a signal from the brake switch is input. Thus, a driving speed is automatically controlled by the motor reflecting a driver's physical condition or intention but without relying on an accelerator.

摘要： PROBLEM TO BE SOLVED: To reduce torque shocks generated in an AC motor at the switching of a square wave voltage phase control mode and a PWM current control mode. SOLUTION: This drive control equipment is so constituted that a switching command can be supplied selectively to an inverter 36 from a PWM circuit 30 and a square wave generating part 32. At the switching of both control modes, a quasi-sine wave voltage which has a voltage amplitude |V| formed by a voltage amplitude controller 16 and a voltage phase ψ formed by a voltage phase controller 18 is applied to a motor 38, and control is so performed that the torque of the motor 38 remains constant.

摘要： A pulse width modulator (PWM) circuit for generating pulses to enable a driver control unit to drive a pair of switching circuits for an electric motor including an input section for receiving an N bit digitized input signal to be modulated and a PWM counter for continuously counting up from zero to a predetermined number and back down to zero, the PWM counter generating a digitized triangular waveform having N bits of resolution corresponding to the predetermined number. A compare unit receives and compares the digitized input signal and the digitized triangular waveform to produce an output pulse and a dead-time generator unit produces a first pulse and a second pulse from the output pulse produced from the compare unit. The first and second pulses each drives a corresponding one of the switching circuits and the first and second pulses have different transition times relative to each other. A built-in test (BIT) circuit provides BIT input signals corresponding to the first and second pulses to verify correct operation of the PWM circuit including a feed back path from the driver control unit, the driver control unit having a higher level of integration than the PWM circuit, and the BIT input signals providing individual control of each of the PWM signals.

摘要： PROBLEM TO BE SOLVED: To lower the switching frequency of an inverter and lessen the switching loss, to suppress heat generation by forcedly switching the pulse mode into another pulse mode one stage lower than before, under such a situation that the train speed is balanced. SOLUTION: With the electric car, the pulse mode of an inverter is set in multistages by pulse mode setting means 41a-41e, when driving a motor for drive of the train by an inverter of variable frequency variable voltage control. Now, when the train speed is balanced in such a situation while the train is going up an accent, a speed balance judging means Pf1 judges that the train speed is balanced, and based on this judgment result, the pulse mode forcedly switching means 44a-44b and 45a-45b forcedly switch the pulse modes set by the pulse mode setting means 41a-44d over to a pulse mode, one stage lower than before.
