摘要： PROBLEM TO BE SOLVED: To provide a method for measuring reactor loss capable of simply calculating an iron loss in one ripple period symmetrical with respect to time T/2 over all the output periods of a PWM inverter, and capable of precisely calculating only an iron loss generated by switching ripples.
SOLUTION: A predetermined-frequency current component and a predetermined-frequency voltage component are acquired from the current and the terminal-to-terminal voltage of a reactor which change by PWM switching; time points of crossing of the reactor current with the predetermined-frequency current component are acquired, and the interval between odd number-th or even number-th cross points in time adjoining each other makes a loss calculation period. By subtracting the area αb of a B-H curve Γb drawn by the intensity of a magnetic field calculated from the predetermined-frequency current component and a magnetic flux density calculated from the predetermined-frequency voltage component, from the area α of a B-H curve Γ by the intensity H of a magnetic field calculated from a reactor current corresponding to the loss calculation period and a magnetic flux density B calculated from the terminal-to-terminal voltage of the reactor, the reactor loss in the loss calculation period is obtained.

摘要： PROBLEM TO BE SOLVED: To generate a high-precision frequency-variable rectangular pulse signal while suppressing generation of jitter in a frequency-variable signal generating apparatus using a general-purpose DDS (direct digital synthesizer). SOLUTION: The frequency-variable signal generating apparatus comprises a DDS 1 which outputs an analog signal of a frequency to be changed in accordance with a setting value; a comparator 3 which generates a first rectangular pulse signal of the frequency from the analog signal; a programmable frequency divider 41 which outputs a second rectangular pulse signal frequency-dividing the first rectangular pulse signal in a set frequency dividing ratio; and a control unit 4. When changing the frequency to a higher frequency domain side, the first rectangular pulse signal is defined as an output signal So for the frequency divider. When changing the frequency to a lower frequency domain side, the setting value is changed and controlled to a value of the frequency dividing ratio multiple for the DDS, the first rectangular pulse signal having a frequency of the frequency dividing ratio multiple is generated, and the second rectangular pulse signal of the relevant frequency divided in the relevant frequency dividing ratio in the frequency divider is defined as the output signal So.

摘要： PROBLEM TO BE SOLVED: To provide a waveform display device which has no misread of signal waveform, can accelerate updating of waveform representation and achieve real time display causing no dead time.
SOLUTION: The waveform display device has bitmap memories A and B. A memory controller 61 writes digital waveform data taken from an AD converter 2 at every frame period in the memory A or the memory B by turns. The written waveform data is read out in the frame period when writing operation of waveform data in the memory A or the memory B is not done. The read-out data is made an image data as it is and the waveform is indicated on the display 5. Writing in the memory A or the memory B in each frame period is initiated at every trigger signal input to the memory controller 61 and the waveform data of the memory length of memories A and B is written in. When data is read out as raster from the memory A or the memory B at every frame period in turn, an image data for one picture is produced.
