How do rectifiers and transformers work in a PC power supply?
There is no transformer used in PC power supply. There is rectifier used to rectify or convert AC input voltage into DC output voltage.Transformer based rectifier produces some spikes at the output DC voltage, hencethey uses SMPS (Switch Mode Power Supply) to avoid spikes to the output DC voltage and get a smooth DC voltage.
What supplies power to a computer?
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
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 pins go to power load and ground on a bridge rectifier for building a DC power supply?
The two pins with the ~ symbol are for the AC input and the + and - are for the pulsing DC output
What is the type of transformer used to step down 230v ac to 48vdc?
A transformer alone cannot accomplish this. Transformers do not output DC directly, only AC. For DC output, additional components (rectifier, filter capacitor) are necessary. This would be properly called a DC power supply rather than just a transformer. To specify the proper power supply, you need at a minimum the input voltage (AC), the input frequency, the output voltage (DC), and the output current.
Full form of DC power supply?
DC Power is Direct Current Power Supply.
A DC ground wire coming from a power supply output is typically what color?
Typically black. DC +ve wire color typically red or brown.
The small amount of ac signal present on the output of a filtering network for a dc power supply is known as?
Ripple.
Which multimeter setting to test power supply of a computer?
That depends on what you're testing it for. You would mostly use the volt meter settings to test for proper voltage output at the connectors coming out of the power supply. After verifying the expected volt output from a suspect connector, You should, in case you are wrong or a short is present, start with the highest voltage AC settings first and then reduce to lower settings and DC to confirm proper outputs.
How can an ac generator be converted to DC generator?
It may not be possible to physically convert AC generator to DC generator. What can be done is that 'Rectifier' of suitable capacity can be connected to the out put of AC generator to get DC supply.
Is the metro rail train using ac or dc power supply?
dc power supply
What is the value of ripple in the ideal dc power supply?
In an ideal DC power supply, there is no ripple.
