The power distribution systems of the future will require Solid-State Power Controllers (SSPCs) instead of the less reliable electro-mechanical circuit breakers. The power distribution systems of tomorrow will rely on computer intervention to off-load crews, improve fault handling, and improve system reliability, while protecting the wire and load. The growing diversity of applications and system architectures requires component SSPC manufacturers to offer many advanced features to meet the system designers demands. This paper will focus on the key SSPC features that are being demanded today. To be highlighted are: true I2T protection, Status reporting, BIT, controlled turn-on/off time, leakage current clamp protection, instant trip vs.current limiting, just to mention a few key items. This paper will review the advantages and trade-offs as to their impact on weight, size, safety, and the relative cost.

This paper describes the performance, physical and electrical characteristics of a series of new, very large scale integrated (VLSI) components. These devices fully support MIL-STD-1553 and a variety of computer/microprocesor based subsystems. A new low power transceiver, and protocol for Bus Controller, Remote Terminal and Monitor Modes of operation plus a computer I/O to a central, host processor is included. A discussion of the VLSI special technologies and features is covered. Features such a3 size, packaging options, radiation hardness, power and reliability considerations will be explored. The special programming options and subsystem interface considerations which facilitate a broad array of applications is thoroughly discussed.

This paper describes the performance, physical and electrical characteristic of a MIL-STD-1553 to MIL-STD-1750A Computer Interface. The BOS-65600, Dual Redundant Remote Terminal Unit (RTU), Bus Controller (BC) and Bus Monitor (MT), along with the BUS-66300 Microprocessor Interface Unit are the main building blocks. This combination will support the Fairchild F9450A or McDonnell Douglas (MDAC-281) MIL-STD-1750A Computers. They will also interface with any sixteen bit microprocessor with a minimum of support circuitry. Refer to Figure 1, RTU/BC/MT, MIL-STD-1553 to MIL-STD-1750A Computer Interface. The custom monolithic LSI components used in these special Superhybrids will be discussed. An explanation of the special shared Dual Access Memory approach will be included. This discussion will show how a dedicated memory can off-load the host CPU and fully support all 1553 transfers.
