What does the power intverter in a power supply do?

The primary function of the power inverter in a power supply is to change the direct current (DC) to the alternating current (AC). The design of the power inverter is dependent on the input voltage, output voltage and frequency, meaning that the inverter could be solely electronic or may have a combination of electronic circuits and mechanical effects.

Define the term regulation as applied to dc power supply?

change in load voltage or output voltage changes in load current


What type of power does a power supply convert to?

A power supply is generally only converting the mains voltage down to a lower voltage suitable for low voltage equipment. It turns 120 v into 18v or 12v or 5v or any other voltage it is specified for. In most countries outside US, we have 220 volt AC in the mains. Power is however power. One could say that Voltage is the speed of which the power run. A power supply generally slows down the speed of electricity. Regards.


How to control motor rpm?

For AC motor, you can change motor RPM by changing its supply voltage or by changing supply frequency. For DC motor, you can change motor speed by controlling armatyre voltage or field current.


What are travel voltage converters used for?

There are many uses of travel voltage converters. Travel voltage converters allow one to change the voltage of an electrical power source. This product can be combined with other components to create a power supply.


Can the power supply provide a negative voltage output?

Yes. Depending on the design, the power supply can provide any voltage desired.


What is line regulation?

Line regulation is a measure of the ability of the power supply to maintain its output voltage given changes in the input line voltage. Line regulation is expressed as percent of change in the output voltage relative to the change in the input line voltage.


When do you need to convert the voltage for appliances?

You need to convert the voltage if your appliance requires less voltage than you power supply. example: appliances is 110V and power supply is 220V.


Which voltages are supported by a Toshiba power supply?

The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and packaging will state voltage recommended for the product.


What happens to the applied voltage when a change in circuit resistance occurs?

When a dc supply is connected to a resistor, current flows. The current in amps is equal to the supply voltage divided by the resistance in ohms. The power used is the voltage times the current, and that appears as heat in the resistor, which might become hot to touch.
