Solid-State Power Supplies for Turbine Control and Instrumentation

A control system manufacturer reviews his applications of purchased solid-state power supplies (with emphasis on dc-to-ac inverters) and indicates areas that the customer and manufacturer of power supplies should stress in order to increase reliability. System reliability, in many cases, can be aided by clear specifications and an exploring engineering analysis of load characteristics and distribution. The analysis is critical and should consider advantages or disadvantages of loads being ac versus dc.
