Abstract :
Carrier Corp. represents a potentially large market for power electronics. We sell, annually, approximately one billion dollars worth of electro-mechanical equipment to consumer, commercial, and industrial markets. We purchase about $84 million worth of electrical equipment, including over $20 million worth of controls, mostly relays, contactors, and switches. A small portion of that $20 million is now electronic, mostly temperature controls and motor overload protectors. Potential applications include solid-state reduced-voltage starters for centrifugal compressors. The two major considerations in qualifying any electronic product are cost and reliability.
