20、o provide a common ground for understanding between systems engineers andtransformer design engineers. Little published data on transformers is directly useful to engineers designingsystems involving feedback loops. Phase and frequency response data are needed on transformers (and othercomponents) u

21、sed in these systems. It is the hope that this standard will eventually influence transformermanufacturers to include such information in their published data on wide-band frequency transformers.This standard is a combination of two original standards: IEEE Std 111-1971 and IEEE Std 264-1977. Bothof

22、 these standards were first issued as trial-use documents in 1962 and 1965, respectively. These trial usedocuments were prepared under the chairmanship of A.D. Hasley and J.P. Whistler, respectively.At the time this standard was approved, the frequency range subcommittee of the Electronics Transform

31、s to electronics wide-band transformers transmitting power within a wide band offrequencies covering typically at least one decade in the frequency spectrum. It is not intended to apply totransformers optimized to operate within a narrow band of frequencies. Transformers used in, or in conjunc-tion

32、with, wire line communication facilities serving power stations are excluded due to the special protec-tion requirements involved. Provision is made for including data for use in the design of feedback amplifiersand control networks, or other circuits in which the knowledge of the transformer amplit

33、ude and phase-frequency response is needed by the system designer. These transformers are required to transform voltagewithin specified tolerances of amplitude and phase when operating between specified impedances. Guides toapplication and test procedures are included. The annexes within this standa

34、rd contain certain precautionsand recommended practices.This standard also pertains to hybrid transformers, primarily used in the telecommunications industry. Thehybrid transformer is a wide-band transformer used in a manner which makes it part of a capacitance, resis-tance, and/or inductance networ

35、k, and it must have characteristics which permit it to match the network forproper overall performance.1.2 Typical types of transformers to which this standard applies1.2.1 Audio frequency transformersAudio frequency transformers may cover a limited frequency range such as that used in voice communi

36、ca-tions, or may cover a part or all of the frequencies from 5 Hz to 100 000 Hz when used in high fidelity orsimilar amplifiers. Voltages or signals correspond directly to speech or music amplitude and phase variationswithin this range of frequencies. Performance characteristics one or more octaves

37、beyond the specified rangemay be of interest and specified. Feedback and other windings or taps may be incorporated in the design.The mode or class of amplifier operation (i.e., Class A, B, AB, etc.) must be recognized and taken intoconsideration.IEEEStd 111-2000 IEEE STANDARD FOR WIDE-BAND2Copyrigh

All rights reserved.1.2.2 Transducer service transformers Transducer service transformers are stepdown ratio transformers having one or more secondary windingswith or without center taps. The load impedance may be permitted to vary with frequency or with otherparameters, but the transfo

39、rmer performance is generally based on a specific load impedance.1.2.3 Random noise transformersRandom noise transformers are used in vibration machine applications. They are subject to random signalsof varying amplitude and duration. Response may be expressed in terms of the frequency spectrum but

40、theamplitude variation allowable over the relevant frequency range is much greater than for audio-frequencytransformers because of the Gaussian distribution of random noise. Random noise transformers are oftenincluded in feedback loops. When included in such a loop, their amplitude and phase respons

41、e is of interestand all of the problems listed in 9.3 must be solved in addition to producing a transformer capable ofhandling the amplitude of random noise.1.2.4 Modulation transformersModulation transformers are used in amplitude-modulated transmitters and may employ a modulationinductor to bypass

42、 the final amplifier supply current.The transformer is used in a manner which makes it part of a capacitance, resistance, and inductance net-work, and it must have characteristics which permit it to match the network for proper overall performance.Phase angle, frequency response, and impedances are

43、important measurements and are required to be madein the actual or substitute network with the major elements in place to establish performance. Modulationtransformers are usually designed for specific applications and large units are not considered suitable forgeneral purpose use.1.2.5 Driver trans

44、formersDriver transformers are used to supply power to the control elements of Class AB2and Class B2amplifiertubes and transistors.1.2.6 Line-matching transformers Line-matching transformers are used where power is received at one impedance level and delivered atanother.1.2.7 Load-matching autotrans

45、formers Load-matching autotransformers are used where power is received at one impedance level and provides out-put tabs at various impedances, and vice versa.1.2.8 Control-system transformersControl-system transformers are used in open- or closed-loop (feedback) control systems. The transformersuse

46、d in the closed-loop system are subject to signals of a definite carrier frequency, modulated in accordancewith error signals imposed by the control system requirements. The response of these transformers to controlsignals may be expressed either in terms of frequency and phase or in Laplace terms.

47、In this standard, thephase and amplitude frequency response terms are used.IEEE(GREATER THAN 1DECADE) TRANSFORMERS Std 111-2000Copyright 2001 IEEE.
