Advanced Energy Industries, Inc., together with its subsidiaries, designs, manufactures, sells, and supports power conversion products that transform power into various usable forms. It offers thin-film deposition power conversion systems, including direct current (DC), pulsed DC mid frequency, and radio frequency (RF) power supplies, as well as matching networks, remote plasma sources for reactive gas applications, and RF instrumentation; and thermal instrumentation products that provide temperature measurement solutions for applications in which time-temperature cycles affect material properties, productivity, and yield. The company also provides solar power inverters, which provide a transformer-based or transformerless grid-tie photovoltaic (PV) solution to convert renewable solar power into electrical power, as well as integrated monitoring and performance measurement of PV installations. Its power conversion systems are used by semiconductor, solar panel, and similar thin-film manufacturers, such as flat panel display, data storage, industrial hard coating and ophthalmic optical coating equipment makers, and architectural glass manufacturers; thermal instrumentation products are used in rapid thermal processing, chemical vapor deposition, and other semiconductor and solar applications requiring non-contact temperature measurement by the semiconductor, solar panels, and light emitting diode industries; and solar inverters are used in the residential, commercial, and utility-scale solar projects and installations. In addition, the company offers repair services, conversions, upgrades, and refurbishment services, as well as operations and maintenance service plans for individual PV sites. Advanced Energy Industries, Inc. sells its products through direct sales force, independent sales representatives, and distributors in North America, Europe, and Asia. The company was founded in 1981 and is headquartered in Fort Collins, Colorado.
