What is an automatic voltage regulator (AVR)?
An AVR, or automatic voltage regulator, is primarily a solid-state electronic gadget employed in diesel generators. Its purpose is to automatically uphold the generator output terminal voltage at a predetermined value, particularly during variations in the generator load or changes in the operating temperature of the generator. In essence, the AVR serves as a crucial component of the alternator’s excitation system.
China BISON AVR ensures the stability of the generator’s output, which often experiences uneven loads. It also helps distribute the reactive load across multiple parallel generators, a process known as voltage droop. Moreover, it assists the generator when it is overloaded.
why are automatic voltage regulator (AVR) important for generators?
Unregulated generators, those without an automatic voltage regulator (AVR), often have issues providing sufficient power to all connected devices or equipment. This issue arises from their inability to control or stabilize voltage, resulting in a continuous drop in terminal voltage as power demand increases.
If a generator can’t maintain a consistent voltage, its performance can be significantly affected. Such inconsistency can also harm utilities, machinery, or equipment powered by the generator.
An AVR is vital for improving your generator’s performance and lifespan, as well as the lifespan of the items it powers. It guarantees a steady voltage output, despite fluctuations in the load current. This helps to avoid or even prevent potential damage to appliances, machines, and equipment caused by these fluctuations.
what is the function of an automatic voltage regulator (AVR)?
Automatic voltage regulators (AVRs) primarily serve to regulate generator voltage automatically, maintaining a steady output within the correct voltage range for your generator, irrespective of the load’s current draw.
In addition to voltage regulation, AVRs also:
- Guard against electrical surges, spikes, and generator overloads
- Prevent short circuits by assisting the generator in managing overloads
- Distribute reactive load among generators operating in parallel
- Provide under-frequency protection and soft-start support
- Protect the alternator field from over-excitation damage
Generator AVR buying guide
To ensure stable and reliable operation of generators, automatic voltage regulators (AVRs) are integral components. This important device controls the generator’s voltage output, preventing fluctuations that could damage your equipment or the generator itself. Whether you are a first-time buyer or looking to replace your existing AVR, China BISON will guide you through the complex world of the Generator AVR. BISON will cover everything from the basics of how an AVR works, to key features to be aware of, and even some advice to help you make an informed decision. Let’s dig deeper!
Types of automatic voltage regulators
AVRs, or Automatic Voltage Regulators, are available in a broad and constantly advancing array suited to accommodate diverse power systems. These essential devices, key in preserving consistent voltage levels, range from the classic electromechanical AVRs using mechanical elements, to the more sophisticated microprocessor-based and digital AVRs that employ rapid mathematical operations for regulating voltage. Other types include servo motor AVRs and computer-controlled regulators that adapt to changes in electrical load and voltage, providing greater precision and performance. Follow along with China BISON and learn that each type has its unique features and benefits.
AVRs of the electromechanical type
These are the most ancient AVRs, relying on mechanical elements like rotors and stators for voltage regulation. They possess a relatively straightforward design and can manage various power and voltage levels.
Static type AVRs
These employ solid-state elements such as thyristors and transistors to manage a generator’s voltage output. While they are more reliable and efficient compared to electromechanical AVRs, they may lack durability under extreme conditions.
Microprocessor-based AVRs
These represent the most sophisticated AVRs, utilizing digital controllers, predominantly microprocessors, to control voltage output. They provide the highest accuracy level and can be programmed to adjust to different operational conditions.
Digital AVRs
These are similar to Microprocessor-based AVRs, but rather than using a microprocessor for digital control, they use a digital signal processor, which excels at high-speed mathematical operations.
Servo Motor AVR
This AVR variant employs a servomotor that modifies the generator’s excitation in response to electrical load and voltage shifts. It uses a control loop for enhanced accuracy and performance.
Computer-controlled regulator
As the name suggests, it primarily relies on the overall system’s load current as conveyed to the generating computer. The engine computer ensures the magnetic field circuit is activated and deactivated according to the set value, allowing the electrical system to function normally.
Given the importance of the AVR in a generator, purchasing from a trusted China generator manufacturer such as China BISON is highly recommended. This guarantees the precision of the product details, and you can have confidence in its upkeep and long-term durability.
An Automatic Voltage Regulator (AVR) is a tool that automatically sustains a consistent voltage level in an electrical power system.
How does a generator AVR work?
The primary role of an AVR is to regulate the output voltage of a generator. It achieves this by first detecting the voltage from the generator terminals, then comparing it with a predefined stable reference value to identify any error signals. If there is a difference between these two values, the ACR modifies the field current by either increasing or decreasing the current flow to the exciter stator. This process results in either a lower or higher voltage at the main stator terminals.
Essentially, the AVR acts as a control mechanism, ensuring the generator’s voltage output stays within a specific range. This prevents the generator voltage from dropping so low that it might cause connected electrical equipment or devices to malfunction. Additionally, it protects the generator from inadequate battery charge.
Changes in the generator’s speed – often resulting from alterations in the engine’s speed given the fixed transmission ratio between the generator and the engine – necessitate adjustments in the generator’s output. Maintaining a consistent voltage during these changes safeguards both the electrical equipment receiving the power and the generator battery.

generator AVR FAQ lists
What causes AVR failure?
AVR failure is typically caused by a decline in the performance of the generator’s driving motor, which causes unstable engine rotation under electrical load. This produces voltage fluctuations that force the AVR to operate irregularly, ultimately damaging the unit. Other causes include overheating, moisture ingress, and sustained overload conditions.
For detailed information, please refer to “Causes of damaged voltage regulator (AVR).”
Do all generators have an AVR?
Upon purchasing a new generator, it comes with an AVR as part of the generating set. The specific AVR included depends on the kind of accessories the generator is used with. Therefore, every generator has its own unique AVR.
How is voltage regulated in a generator?
The generator’s excitation system facilitates this operation. It regulates the magnetic field and oversees the output of the generator to sustain the required voltage. As the generator’s load heightens, the current flow proportionally increases, resulting in a decrease in voltage.
For detailed information, please refer to “How to adjust generator voltage.”
Are AVRs available in different designs?
Yes. While many AVRs look similar in form factor, they differ significantly in their internal design — including analog vs. digital control, excitation type (shunt, PMG, auxiliary winding), and voltage/power ratings. It is important to match the correct AVR to your specific generator model and excitation system.
