PURPOSE:To prevent malfunction due to a noise, surge, vibration, impact, etc., by connecting a rectifying circuit to a detection phase and detecting a phase direction by a voltage level detector provided on a DC side. CONSTITUTION:When a power source is connected to the circuit where a ...
This is a phase detector, designed to perform phase sequence checks and live line checks of a 3-phase circuit using a static induction voltage clip. The static induction voltage clips are used to be able to clip on a cladded wire.
A sequential phase-frequency detector circuit using precharged logic and a minimum number of transistors is suitable for use in a delay locked loop because of insensitivity to a stuck delay line output signal. The detector receives standard REFERENCE and LOCAL input signals and provides UP and ...
摘要: PROBLEM TO BE SOLVED: To prevent short-circuiting accidents, even if clips are contacted in a voltage/phase rotation checker that makes clips of detectors connected in a conductor exposed section of an electric line and use the same....
PURPOSE:To find easily a phase current by approximation by detecting line currents of respective phases by line current detectors and performing arithmetic by a line current-phase current converting circuit according to a specific equation. CONSTITUTION:The line currents (a), (b), and (c) of the...

The circuit shown utilizes the fact that the second harmonic of the carrier contains no phase shift (when the frequency is doubled, a 180° phase shift becomes a 360° phase shift, that is, no phase shift at all). The incoming frequency is doubled by the times-two multiplier, x2, ...
Control circuit for stopping Brushless DC motors A DC motor is provided with a bidirectional driving circuit, a servo circuit for controlling the driving circuit, and a rotation detector associated with the motor shaft to provide a phase signal that depends, in magnitude and polarity... M Sakai...
