3-2 THE BASIC POWER SUPPLY Figure 3-1 shows the block diagram of the basic power supply. Most power supplies are made up of four basic sections. A TRANSFORMER a RECTIFIER a FILTER and a REGULATOR.
Block diagram of a basic power supply. As you can see the first section is the TRANSFORMER. Power stage sometimes called a step-down power stage.
Power supply designers choose the buck power stage because the output voltage is always less than the input voltage in the same polarity and is not isolated from the input. The input current for a buck power stage is. The different stages of the amplifier require different voltage absorb a different amount of current and are more or less sensitive to noise eg.
Hum produced by the power supply itself. The power supply unit has to consider these differences. The power supply unit is composed of a power transformer followed by a rectifier and a sequence of smoothing.
Parts of a Power Supply. Static device that transfers electrical energy without affecting the frequency. First step of converting AC power from wall socket to DC power needed for device.
Used to step up or step down the AC voltage to a uniform charge while isolating it from the AC power. Power Supply block Diagram. Many electronic circuits need a direct current DC voltage source but what we commonly find are voltage sources of alternating current AC.
In order to achieve a direct current voltage source the alternating current input must follow a conversion process like the one shown in the power supply block diagram below. This is all about different types of power supplies which include linear power supplies switching mode power supply uninterrupted power supply. Furthermore to implement electronics and electrical projects or any information regarding the types of power supply fell free to give your feedback to give your suggestions comments in the comment section below.
Describe the principles of transformers used in basic power supplies. Primary and secondary voltages. Describe the principles of rectification used in basic power supplies.
Rectifier - converts AC to DC but the DC output is varying. Smoothing - smooths the DC from varying greatly to a small ripple. Regulator - eliminates ripple by setting DC output to a fixed voltage.
Power supplies made from these blocks are described below with a circuit diagram and a graph of their output. The design of switching power supplies requires significant attention to detail from component placement and thermal analysis to careful testing for a wide range of operating conditions. Power supply designers choose the boost power stage because the required output voltage is always higher than the input voltage is the same polarity and is not isolated from the input.
The input current for a boost power stage is continuous or non-pulsating because the input current is the same as the inductor current. The power supply is often forgotten when it comes to diagnosing computer problems but testing your power supply first can save you a lot of troubleshooting headaches down the road. If your computer experiences Blue Screen of Death crashes hard drive errors or just plain wont boot you may be dealing with a faulty power supply.
