Initially, an automatic voltage regulator (AVR) for generators was an electro-mechanical device with a variable resistance as an output. Generators with a dc exciter were often provided with the Brown Boveri (BBC) Universal Voltage Regulator. After the development of the power electronics, electronic voltage regulators with one or more thyristors became available.

For power factor of VAR control, limiters, diode fault detection and / or protection separate modules were used. In the 90 manufacturers bring the first digital voltage regulators on the market. These controllers contain more integrated features, but for many features separate modules are still required.

The modern, state-of-the-art integrated systems do not only contain automatic voltage control, but moreover an extended functionality. The Brown Boveri Company (BBC, now ABB) electro-mechanical Universal Voltage Regulator was widely used for generators with a dc exciter. Peugeot Al4 Gearbox Repair Manual download. A number of voltage regulator manufacturers are given below. download 96 Chevy 5 7 Vortec Service Manual torrent. Brush Prismic type A12 and A32 are modern, multifunctional excitation controllers, suitable for generators with brushless excitation and a PMG. For static exciters and other excitation systems Brush provides the Prismic A50. Precursors are the A10 (digital), A30 and MicroAVR (both partly digital) and the MAVR (analog). PEAVR, STAVR, BAVR and TDES AVR are electronic models that Brush BEM in Engeland manufactured in the past.
