Component that will keep the voltage steady?
Hi, is there a component that will keep the voltage in the circuit steady? So if i use for example solar cells as a power source and i only want lets say 3 volts supplied to my circuit but its really sunny day and the voltage is going from 6-12V is there something like a resistor that keeps the same voltage in the circuit? Obviously i cannot use a normal resistor because it might be suitable for 8V but too strong for 6V or too weak for 12V. Hope u understand what a am asking lol thx
Although a resistor will drop some voltage, it won't regulate the voltage. You need a voltage regulator circuit, which is an active circuit. It continuously senses the voltage by comparing it to a fixed point, and when the voltage increases, the active component (like a transistor) conducts more to shunt enough current to drop the voltage. When the voltage decreases, the transistor conducts less so that less voltage is shunted away. The transistor acts like an automatically variable resistor (which is how the transistor was originally named). These days, voltage regulator (VR) chips are commonly available for a variety of fixed voltages. Your only necessity is to make sure they're rated for the maximum current they'll be working with.
Power Inverters
Power Inverters
Most of the time, when the electrical power gets interrupted due to a heavy downpour or a severe storm or any other reason, the reliable source of power when you require it the most is the power inverter. Power inverter is designed to answer these power outages and pose as a reliable and economic alternate source of electricity. That is why, the power inverters have enjoyed great popularity since their introduction in the market.
Power inverters are designed to convert direct current to alternating current. Most of the power inverters work by converting 12 Volt DC power into 110 volts AC. With the use of power Inverters you can run household appliances from a car or any other DC source in areas where there is no electricity. Power inverters are available in two categories – The True Sine Wave Power Inverters and the Modified Sine Wave Power inverters.
Of these the True sine wave power inverters provide utility grade power but are expensive and can power almost anything including laser printers and fax machines. The sine wave power inverter is most suitable to operate higher-end electronic equipment which can be damaged by other inverters. On the other hand, the Modified sine waves are the most common types of power inverters available today. Like its counterpart, this inverter can sufficiently power most household appliances and power tools. It is more economical compared to the true sine wave inverter, but may ask for certain compromises with some loads such as microwave ovens, laser printers, clocks and cordless tool chargers.
Power inverters are widely used for large assortment of applications, from small power supplies for a computer to large industrial applications to transport bulk power. One of the most widely used applications of Power Inverters include running television sets, microwaves and other household appliances and charging cell phones, laptops from a car’s cigarette lighter outlet and running power tools from a 12 volt battery on jobsites where electricity is not available.
If you are looking forward to buy a power inverter, remember that most of your household electrical devices will run perfectly on both the type of wave form. Most of the users who are using a power inverter to run a laptop, a/c cell phone charger, fan, or camera agree that a modified-sine wave power inverter that operates through the cigarette lighter socket is the easiest to use. While you buy a power inverter it is suggested to choose an inverter that is rated under 300 watts when using the 12-volt cigarette lighter socket found in most vehicles. This is because after reaching 300 watts of draw on the inverter, the fuses in your car might blow off. Such power inverters are a great choice for dashboarders who would like an easy solution to power their devices. It has only one outlet, but since plugging it into a 12 volt socket is all that is required for operation. This little inverter can supply 140 watts of continuous operation and has a built-in surge protector.
