FIELD: electricity.
SUBSTANCE: emergency shutdown in the claimed device is ensured only when long-term conditions of dynamic current limitation are observed thus authenticity in diagnostics is reached for the conditions requiring the elimination of the detected failure. To this end in the suggested multichannel amplifier of D class comprised of a multichannel sawtooth voltage generator and k channel for key amplification with a transformer output and output current sensors in the composition of each ith channel an additional summator and threshold attenuator are introduced, and a multichannel inhibitor circuit and time discriminator are also used.
EFFECT: improved energy efficiency for the multichannel amplifier of D class at uninterrupted operation in conditions of extreme modes and expanded functionalities for its usage in wideband hydroacoustic transmission paths (HATP).
