### Introduction

An exciter generally models, regulates, and sustains
device internal voltage.


### Types
There are a few standard Exciter models
- ESAC6A Excitation Model (See [ESAC6A](esac6-a/index.md))
- IEEE Type 1 Excitation Model (See [IEEET1](ieeet1/index.md))
- IEEE DC1 Excitation Model (See [EXDC1](exdc1/index.md))
- ESDC2A Excitation Model (See [ESDC2A](esdc2-a/index.md))
- EXAC1 Excitation Model (See [EXAC1](exac1/index.md))
- IEEE ST4B Excitation Model (See [ESST4B](esst4-b/index.md))
- SCRX Excitation Model (See [SCRX](scrx/index.md))
- EXAC2 Excitation Model (See [EXAC2](exac2/index.md))
- EXPIC1 Excitation Model (See [EXPIC1](expic1/index.md))
- Simplified Excitation System Model (See [SEXS-PTI](sexs-pti/index.md))
