CHAPTER 11

DC Generators When operated as a generator, the armature of the DC machine is driven by a prime mover. When the armature coils move through the flux created by the stator field, a voltage is induced in them. The voltage in a coil is a function of the velocity of the coil through the flux, the length of the coil, and the flux density.

EE 340 Spring 2011 - UNLV

• The exciter generator’s 3-phase output is rectified to DC by a 3-phase rectifier (mounted on the shaft) and fed into the main DC field circuit. • It is possible to adjust the field current on the main machine by controlling the small DC field current of the exciter generator (located on the stator).

2. Generator Basics IEEE

Sep 27, 2016 · Circuit: Generator without a PMG • As the revolving field rotates, residual magnetism in it produces a small ac voltage in the main stator. • The regulator rectifies this voltage and applies dc to the exciter stator. • A three-phase AC voltage appears at the exciter rotor and is in turn rectified by the rotating rectifiers.

DC/AC Pure Sine Wave Inverter

The purpose of a DC/AC power inverter is typically to take DC power supplied by a battery, such as a 12 volt car battery, and transform it into a 120 volt AC power source operating at 60 Hz, emulating the power available at an ordinary household electrical outlet.
