The novel power supply for generating a constant d.c. voltage from a variable a.c. voltage supply line, includes a plurality of switch circuits (10, 12) which monitor voltage levels on respective secondary windings (L,M,H) of a power transformer and as voltage levels change, one of the plurality of switch circuits is selected to charge a capacitor (C1) which provides a range of d.c. voltages which are processed to provide the constant d.c. voltage.

Applications of variable DC power supply?
Variable dc supply is applicable in loads that are variable.
What are the advantages and disadvantages of variable power supply?
A: A variable power supply has no disadvantage since it can replace a fix power supply. The disadvantage will rest with the additional cost to make one.
What are advantages of voltage divider bias over the other types of biasing ci?
You can use more than one type of voltage divider in it. It can sometimes get mixed signals with all the things going on.
What is variable DC supply?
Variable DC power supply is: Variable - you can adjust it DC - direct current, electrons (electricity) flows in only one direction power supply - power supply Together, it's an adjustable one-way power supply Hope you find this useful...
How do you get half of the voltage from a DC supply circuit?
By using a voltage divider, that is two resistors of the same value in series across the DC supply. Half of the supply voltage will be at the point where the two resistors is connected. But how much wattage of those resistors is also an issue.
Applications of variable DC power supply?
Variable dc supply is applicable in loads that are variable.
What are the applications of variable DC power supply?
variable dc supply are used to get desired amount of dc supply
What is voltage divider circuit?
The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.

Food cost fixed or variable?
The cost of all food is variable, depending on supply and demand.
Supply has the potential to contribute to what?
Supply has the potential to contribute to demand. When a product is highly demanded, but the supply is low, a producer can increase their price. This process will increase revenue for the business.
Where can one purchase a variable DC power supply?
You can purchase a variable DC power supply online from retailers such as Amazon. Once on the website, type "Variable D/C Power Supply" into the search field at the top of the page and press enter to bring up the items.

What is the price of the cheapest variable power supply?
The cheapest price the writer was able to obtain for a variable power supply was $45.45 for those customers searching in Canada. If one wants to make a home-made variable power supply, it is possible to buy all the needed parts for about $15.00
How do you make power supply variable?
A variable power supply is one whose output voltage (or current) can be adjusted and therefore set to a desired figure. They are used in development and design odf circuits, eliminating the need for possibly many power supplies of different output voltages. Once a circuit is connected to it, the output would not normally be changed.
