Title: Pulse width modulation type inverter
Inventor: NAKAYAMA SETSUO
IPC: H02M7/48
Filed: 1983-02-16
Abstract: PURPOSE:To reduce the cost of a pulse width modulation type inverter by using a relatively simple element such as a counter and an analog switch, etc. to produce a PWM control signal, thereby simplifying the circuit configuration. CONSTITUTION:A VCO1 outputs a pulse of frequency corresponding to the voltage level of the set value Fv of the output frequency and voltage of an inverter. This output is inputted to an up-down counter 2, and also to a counter 4 through a frequency divider 3. The outputs of counters 2, 4, an inverter 5 and voltage dividers 7, 8 are inputted to pulse width modulators 9U, 9V, 9W, which have analog switches 10-12 and comparators 13, 14. A distributor 15 applies a no control signal to the PWM signals from the modulators 9U, 9V, 9W, sorts and adds the PWM control signals of oblique positive and negative sides, and outputs a PWM control signal of a switching element of an inverter main circuit.

Inventor: ICHIMURA YASUHIKO
IPC: G05D1/02
Filed: 1987-02-06
Abstract: PURPOSE:To cope with a change in target point flexibly by providing a CPU which computes a traveling course from a start point and a target point and an intermediate target storage device which is stored with intermediate target points on the traveling course. CONSTITUTION:The CPU 4 in an automatic traveling course arithmetic unit 3 which receives a target point change command from a center control room 1 receives target point coordinates sent at the same time with the target point change command and the start point position which is already stored by a command receiver 2 and operates a linear equation by using the start point position and target point coordinates to calculate intermediate target points. The operated intermediate target points are stored in the intermediate target storage device 5. Further, when the target point change command is received during the traveling on the course, intermediate points are operated again from the start point to rewrite said intermediate points. Thus, the change of the target point is coped with flexibly and traveling operation is easily automated.
