System Design Factors for Audio Amplifiers.pdf
Taken from the first page: Prior to going into purely technical details, it appears to be desirable that an evalution be made and some conclusions drawn as to why there should be, and why there has been such disparity between the findings of the various A-B listing tests and variously conducted by ably qualified persons and groups; as between engineers and hi-fi enthusiasts on one hand, and the untutored (but honestly discriminating) public on the other.
Transient Peak Power Effect on Diode.pdf
Taken from the first page: Generally, it is common knowledge that when excessive power is dissipated within a diode junction, its junction temperature rises. As it rises beyond the critical limit, the diode would suffer irreversible damage. Although all diodes are specified with maximimum operating temperature, maximum thermal resistance and maximum power dissipation, some diodes still fail during operation despite the appearance that they operate within the maximum ratings. During the transient period, abnormally high current and voltage spikes may be present, thus resulting in high peak power (Ppk) that the diodes must be capable of withstanding. From the average standpoint, the operating average may be within the maximum rating. Presented here is a discussion of the thermal stability from the transient peak power standpoint.
Practical Applications of Current Limiting Diodes.pdf
Taken from the first page: The current limiting diode (CLD) or current regulating diode (CRD) has been available since the early 1960’s. Unfortunately, despite its simplicity and distinct advantages over conventional transistorized applications, it has seen only limited use. One reason may be designers’ lack of familiarity with practical circuit design techniques involved with its use. Another reason may be that although many papers have been published on the device, most have dealt primarily with solid-state theory, rather than with practical applications. Therefore, it is the purpose of this paper to focus on how this device is used, rather than on what it is.
Boosting the Current Limit of Current Limiting Diodes.pdf
It would not make any practical sense to use 66 CLDs in parallel to attain 1 amp or 100 CLDs to attain 1.5 Amp. Therefore, the need for a practical solution to achieve high current limit is evident.
