摘要： A reactor having a predetermined small capacity is connected to a rectifier, and a capacitor having a predetermined small capacity is connected between DC bus lines of the inverter. A PN voltage corrector calculates a ratio of the DC voltage detection value of the inverter obtained by the PN voltage detector to a predetermined DC voltage reference value of the inverter to thereby generate a PN voltage correction factor. A beat amount corrector calculates a fluctuation amount of the motor current from the motor current detection value obtained by the motor current detector and generates a reverse phase component of the motor current fluctuation amount. Thus, a small, light and low-cost inverter controller can be implemented.

摘要： A cursor movement control a screen-segmented display apparatus in which the cursor is moved line by line within one divided section. The apparatus comprises a horizontal cursor register for storing the horizontal position of the cursor on display, a vertical cursor register for storing the vertical position of the cursor on display, a starting column register for storing the cursor starting column on one divided section, and a last column register for storing the cursor last column on the section. The contents of the horizontal cursor register are changed by pulses of an external pulse source generated in response to a command for moving the cursor. When the contents of the horizontal cursor register coincide with that of the last column register, the horizontal cursor register is stored with the starting column of the starting column register and at the same time the contents of the vertical cursor register are changed to set the cursor forward by one line.

摘要： An inverter control device for driving a motor with small size, light weight and low cost is provided. The inverter control device generates PN voltage correction coefficient by dividing the reference DC voltage by the detected DC voltage, and corrects the voltage command of each phase by multiplying the voltage command of each phase obtained by the motor voltage command generator with the PN voltage correction coefficient output from the PN voltage corrector, thus resulting in the corrected motor voltage command. The inverter control device has, in generating PN voltage correction coefficient, a first mode in which the PN voltage correction coefficient is set to 1 when the DC voltage value is more than the reference DC voltage, and a second mode in which the value obtained by dividing the reference DC voltage by the detected DC voltage is set to the PN voltage correction coefficient.
