A voltage regulator is a device that maintains a steady and reliable voltage in a machine

  1. 1. A voltage regulator is a device that maintains a steady and reliable voltage in a machine. It automatically keeps the voltage within a prescribed range. This device is mostly used in the automotive industry. The output voltage is matched to the electrical load in a motor vehicle to ensure compliance to battery charging specifications. The devices are also found in computer supplies and power station generators. Where to buy The regulators can be bought at different electronic shops. E-commerce has been embraced worldwide. Online buying and selling of goods has been made easier. For a good voltage regulator,utsource.net is a recommended site. Here, different types and prices are listed. Types of voltage regulators Various techniques are involved in the automatic regulation of the output levels. The components used help improve efficiency and performance. Voltage regulators vary in price and efficiency. The following types of voltage regulators are available in the market. · Linear regulators In regard to price, they are the most affordable regulators. They are also the easiest to use. They are mainly used low voltage and power systems. In the field of technology, it is often referred to as a voltage divider circuit. This is mainly because the feedback voltage determines the effective series resistance of the regulator. Using a linear regulator has one major limitation. The minimum voltage drop across the regulator is high. The voltage drop is important in the power distribution. A regulator becomes less inefficient when the power difference between the input and output voltage is large. · Switching regulators Compared to linear regulators, switching regulators are more efficient. This device is highly efficient when expecting a wide range of input voltage. The power efficiency of this regulator is very high. The components used in this type of regulators play a major role in determining the overall performance of the regulator. One limitation of the switching regulator is the complicated design. It is easy to interfere with the general performance of the device if one has no full knowledge of how the device works.
  2. 2. · Zener diodes This is the simplest way of controlling the voltage level in a machine. Many people believe that because the linear regulator has fewer components and is easy to use, then it means it is the best. However, the zener diode can use a single component to regulate the voltage adequately. They are limited to low power appliances only. This is mainly because of the limitation they have in handling power. Mostly, a resistor is used to control the current that flows through the diode. How the voltage regulator works A fixed voltage output with a specific magnitude is generated and remains steady even if the input voltage is changed. The regulators use capacitors and smaller inductors to achieve higher frequencies. This causes great noise in the circuit. A switching regulator uses a PWM to control the power input. The duty cycle is controlled by feeding back the output voltage to the PWM controller. For a voltage regulator, output current, input and output voltages are important design specifications.
