Filed: 1989-04-21
Abstract: PURPOSE:To improve the characteristic of a capture range by using an adaptive luminance line emphasis device so as to extract only a carrier signal from an output of a frequency multiplier eliminating a modulation component from an M-phase modulation signal, applying product detection from the carrier signal and a phase modulation signal and eliminating a phase shift from a signal point unable to be eliminated with a phase shifter. CONSTITUTION:A phase modulation signal inputted from a terminal 10 is multiplied by M at a multiplier 1 and a modulation component is eliminated. The output of the multiplier 1 is inputted to an adaptive luminance line emphasis device 2, noise is suppressed and only the carrier component with a frequency of a multiple of M is extracted. A frequency divider 3 reproduces the frequency of the original carrier from the carrier component multiplied by M. The reproduced original carrier signal is subject to multiplication detection with a phase modulation signal at a terminal 10 by a multiple detector 4. The carrier frequency is eliminated from the output of the detector 4 and the phase modulation signal with a fixed phase error from the signal point is obtained, Then the phase shifter 5 is used after the detector 4 to eliminate a fixed phase error thereby demodulating the phase modulation signal.

Abstract: PURPOSE:To prevent a self-arc extinguishing element from damaging by delaying the arc extinguishing signal of two self-arc extinguishing elements to be extinguished for the prescribed period to control the commutation of the element relative to the commutation. CONSTITUTION:A pulse stretcher 9 has a function of expanding the pulse width, does not delay, for example, during the time when the level of the rectangular signal to be inputted rises, but delays only for the time when the level falls. Accordingly, since either one of GTOs 41, 42 of two self-arc extinguishing elements relative to commutation is always ON, the current pathway when the GTO42 is fired is closed before the current pathway when the GTO41 is fired is opened. Therefore, the discharging current by the energy of the like stored in a DC reactor is not flowed to a snubber circuit, but flowed to the GTO main circuit commutated smoothly.
