Why series a resistor with a load for a DC supply circuit?
Good question on a linear power supply a load is not really required since it is nothing but a low band power amplifier. ON a switching type power supply a minimum load is always required so the PWM has something to control to. Also the soft start circuit may blowup waiting for feedback .Critical circuit since it operates for a very short time. however the load is in parallel not in series.
Will a switching power supply work on 277 volts?
Not unless it is rated for that voltage. You can likely find a step down transformer from 277 volt sto 120 volts.
Regulated power supply?
all about regulated power supply
What is power supply?
If it is a computer power supply it is the box that gives the computer its power from the outlet.
Why cmos consume low static power?
CMOS is a dynamic power consumer...whereas BJT consumes power always.... cmos consumes power only while switching from one astate to another state...i.e while switching
Difference between linear power supply and switch mode power supply?
a linear power supply the noise or ripple can be reduced to mv. However it is bulky heavy and inefficient A switching power supply it is easier to filter its output but the hi frequency noise and spikes are not that ease to get rid off. The weight and size can be greatly reduced and the efficiency greatly improved
Types of AC-DC power supply?
Answer for countries in Europe and other world areas running a 50 Hz supply service.AC power supply is 230 v supply used in our homes for switching on fans, bulbs etc. where as DC power supply is used for switching on our laptops, charging our mobiles phones, i pods etc.
How to perform SMPS with circute diagram?
A switched-mode power supply (switching-mode power supply, SMPS, or simply switcher) is an electronic power supply that incorporates a switching regulator in order to be highly efficient in the conversion of electrical power. Like other types of power supplies, an SMPS transfers power from a source like the electrical power grid to a load (e.g., a personal computer) while converting voltage and current characteristics. An SMPS is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage.Unlike a linear power supply, the pass transistor of a switching mode supply switches very quickly (typically between 50 kHz and 1 MHz) between full-on and full-off states, which minimizes wasted energy. Voltage regulation is provided by varying the ratio of on to off time. In contrast, a linear power supply must dissipate the excess voltage to regulate the output. This higher efficiency is the chief advantage of a switch-mode power supply.Switching regulators are used as replacements for the linear regulators when higher efficiency, smaller size or lighter weight are required. They are, however, more complicated, their switching currents can cause electrical noise problems if not carefully suppressed, and simple designs may have a poor power factor.

Differenctiate between linear power supply and switch mode power supply?
A linear power supply typically has a rectifier, filter, and regulator. The rectifier/filter provides pulsating DC that is regulated by the regulator. The trade off is that heat is generated by the regulator and there is often a transformer, making the power supply large and heavy. A switching power supply still has a rectifier and filter, but it often runs directly off of the input AC, without a transformer, saving the weight of a transformer, but generating 160 to 320 volts DC, that must be regulated. The trick in a switching power supply is that a high speed switch supplies power to an inductor. The input of the inductor is also grounded through a high speed, often schottky diode so that, when the switch is off, the inductor has a reverse EMF path to ground. The input of the switch is pulse width modulated, using a regulation scheme that is dependent on output voltage. This works because an inductor resists a change in current, and if the output voltage is stable, it is assumed that the current is stable. The input voltage of the inductor is switching, but the output is fairly stable, requiring only a little bit of noise filtering. The advantage of the switched power supply is that there are no linear drop devices between the filter and the output, i.e. the switch is always fully on or fully off, which means that power dissipation across the switch is much smaller than the equivalent linear regulator. The downside is complexity, but there are fully integrated IC's available today that will do nearly everything, requiring only a few external components. With few, or maybe no, exceptions, most computer power supplies are of the switching regulator style, because you can build them very small, with very little weight, yet provide a lot of power in comparison to a linear power support.
What ac adapter power feature is benificial when traveling to different countries?
auto-switching power supply
What distinguishes a switching power supply from other power supplies?
Normal power supplies are on all the time while switching type are on and off periodically which results in precise control and improved efficiency.
What are advantages of regulated power supply?
Advantage of regulated power supply.
What is Switch mode regulated power supply?
A switching mode power supply works by converting electrical power efficiently by converting voltage and current characteristics. However, it minimizes wasted energy by constantly utilizing on and off states.
