Title: Motor controller employing power inverter
Inventor: NAKADA KIYOSHI
IPC: H02P27/08
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To reduce the size, weight and noise of a motor controller by control ling the carrier frequency of an inverter to decrease in such a back start mode as the inverter frequency crosses zero. SOLUTION: A motor controller comprises means 2 for determining a back start mode from a drive/reverse command FR and a rotor frequency detection value Fr. A carrier frequency setting means 31 outputs a carrier frequency signal Fc depending on the output from the back start decision means 2 and the inverter frequency does not cross zero in normal start mode. In a back start mode, the rotor frequency Fr goes negative temporarily and then goes positive and thereby the inverter frequency Fi has a small value during negative interval of Fr and crosses zero. Consequently, a back start mode can be determined easily and the frequency setting means 31 controls the carrier frequency to decrease during back start period. According to the arrangement, element peak loss can be reduced in back start mode resulting in a small and lightweight motor controller.

Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a system interconnection inverter device that reduces the switching loss of an inverter which converters the interstage voltage of a voltage raise converter into an AC, and that is highly efficient, compact and lightweight. SOLUTION: A voltage raise converter 3 that raises the DC voltage of an input power supply 1 by switching a voltage raise switching element 3c to output a middle-stage voltage VM raises the voltage during, only the period when the voltage VM drops below the absolute value of the AC voltage of a system 2. The raised voltage part of the voltage VM has a waveform of a projecting shape. To maintain this wave form, the capacity of a middle-stage capacitor 4 needs to be several hundreds of μ Fs. The switching loss of the switching element 3c can be reduced by switching it. An inverter 5 that converts the voltage VM into an AC reduces the switching loss by high frequency switching with the arm of switching elements Q1, Q2 only. The arm of the switching elements Q3, Q4 are used for the changeover of polarity.

Abstract: PURPOSE:To obtain a synchronizing signal with simple composition by applying a compared output obtained by comparing an up and down counter output with video data by a digital comparator to a gate circuit, switch-controlling first and second clock signals, and deriving the synchronizing signal from the output terminal of the digital comparator. CONSTITUTION:In the horizontal synchronizing signal part of the video data, when the relation between values (a) and (b) in a figure is a<b, an H-CLK passes through an AND gate 35, an OR gate 38, and an AND gate 37 and executes control so that an up-down counter 34 can be counted down. At this time, an up-down terminal U/D is made into a down D direction. Consequently, in the synchronizing signal part, detailed following up is executed by the H-CLK signal. On the other hand, for a video signal interval, the relation of a>b is obtained, an L-CLK counts up the up-down counter 34, and the U/D is made into an up U direction. Thus, the horizontal synchronizing signal can be obtained from a terminal 41.
