Do you need a power supply for your next big project? If so, it’s important to select the right one. There are many different types of power supplies available, and each has its advantages and disadvantages.
When it comes to peak load applications, you need a power supply to handle the extra stress. But with so many different types of power supplies on the market, how do you choose the best one for your needs? Here we discuss how power supplies work and tips for selecting the best AC-DC power supply for your peak load applications. Let’s start!
How do Power Supplies work?
To provide a steady stream of DC power to your devices, a power supply needs to convert the AC power from your outlet into DC power. This is done using a rectifier, which converts the alternating current (AC) into direct current (DC). The rectifier consists of diodes that only allow current flow in one direction.
After the AC is converted to DC, the power supply uses a filter to smooth out any remaining AC ripple. Ripple fluctuations in voltage can occur when AC is converted to DC. A good filter will minimize the amount of ripple so that it does not interfere with your devices.
Finally, the power supply needs to regulate the DC voltage to the correct level for your devices. This is done using a voltage regulator, which adjusts the DC voltage up or down as needed. Voltage regulators can be linear or switch-mode. Linear regulators work by dissipating excess power as heat, while switch-mode regulators are more efficient because they convert excess power into AC and then into DC.
Now that you understand how power supplies work, you can narrow down your options when choosing one for your devices.
How to Choose Best AC-DC Power Supply for Peak Load Applications?
There are a few things to consider when selecting the best AC-DC power supply for your peak load applications:
- You need to determine the maximum current and voltage your application will require.
- You need to decide what type of power supply topology best suits your application.
- You need to select a power supply with the appropriate features and protections for your specific application.
The type of power supply topology that is best suited for your application will be determined by the loads in your system and the operating conditions of your system. A linear power supply will be the best choice if you have a resistive load. A switched-mode power supply will be the best choice if you have an inductive load.
