IPC: H02P5/747
Filed: 1993-05-12
Abstract: PURPOSE:To control the maximum heating value and reduce the audibility of noise by controlling the inverter circuit for a rotor of the highest output at a low carrier frequency and that for a rotor of the lowest output at a high carrier frequency. CONSTITUTION:Two rotors 2 and 3, large and small, are provided with an inverter circuit 21 and 22, a voltage comparing circuit 23 and 24, a voltage control circuit 25 and 26, and a triangular wave generating circuit 29 and 30, respectively. Current command value is output from a current control circuit according to the torque command value from an integrated control circuit 27. IGBTs 21a and 22a of the inverter circuits are controlled according to the current command value, and the motor winding of each rotor is supplied with three-phase alternating current. The carrier frequency of the triangular wave generating circuits 29 and 30 is set to 1-4.5kHz for the large rotor and 10-20kHz for the small rotor. This reduces the maximum heating value and enables the miniaturization of cooling equipment, and reduces inverter noises under a low load.

Title: Manufacture of thin-film el panel
Inventor: KONISHI YASUO
IPC: H05B33/10
Filed: 1989-05-29
Abstract: PURPOSE:To prevent propagation of breakage by furnishing a level judging part, subjecting the discharge current and charging current to cycle integration pulse by pulse when aging is performed, comparing the difference between the two currents with the normal value, and thereby sensing breakage. CONSTITUTION:When a dielectric breakdown is generated by a positive pulse V+ which is impressed during aging, a charging current I1 flows at the time of rising t5, that is followed by decreasing. When a shortcircuiting discharge is generated immediately thereafter by the dielectric breakdown to cause drop of the voltage, a recovery is made and the voltage is raised again by the charging current I1, which generates dielectric breakdown once again. Repetition of this phenomenon actuates flowing of the breakdown current I3, and cycle integration is made by a cycle integral 16. When the drive voltage V+ is inverted, a discharge current I2 flow, and a level judging part 17 judges the value of I1-I2. This value is approx. zero at normal time and enlarges when breakdown occurs, so that generation of the breakdown can be sensed and propagation thereover is prevented.
