Switching power supplies are electrical power converters that efficiently convert AC or DC input voltage to the desired output voltage. In this blog post, we'll discuss what switching power supplies are, how they work, when you should use them, and who makes the best power supplies for your application.
From understanding how they work and the components they contain to learning about modular designs and UL listed vs UL recognized products—we've got all the information you need to make an informed decision when selecting a switching power supply!
What are Switching Power Supplies?
Switching power supplies, also known as switched-mode power supplies or SMPS, are among the most energy-efficient power supply devices available on the market today. They’re popularly used in personal electronics and have also become increasingly popular for powering industrial equipment.
Unlike linear power supplies, which regulate voltage using a control loop that dissipates energy as heat within a device like a resistor, switching power supplies use high-frequency switching of an electronic circuit to achieve the same regulation of voltage without needing to expend any energy. This makes them much more efficient than linear types of power supply voltage devices.
The switching power supply has come a long way since its invention in the 1950s. Thanks to ever-evolving technology, modern switching power supplies are now more reliable, efficient, and safe than ever before.
Modern switching power supplies are now capable of producing a wide range of voltage depending on the application. They can also be customized with features such as over-voltage protection to prevent any damage due to voltage spikes or surges, further increasing their reliability and safety.
Something you'll see frequently here is the word "modular". But what does modular mean on power supply? Modular power supplies are those that use interchangeable components to achieve the desired voltage output. his makes them much more versatile than regular switching power supplies, allowing them to be used in a wider range of applications. Modular power supplies are also much easier to repair or upgrade than regular switching power supplies.
If designed well, a switching power supply should last longer than other types of power supplies, which helps to reduce the cost of ownership over time. As such, they are popularly used in a variety of industries and applications such as medical devices, home appliances and electronics, telecommunications systems, energy-efficient lighting systems, and more. Now let's explain how switching power supplies work in detail.
How do Switching Power Supplies Work?
So how do switching power supplies work? Understanding how switching power supplies work can be a little tricky for those not familiar with electronics so we'll break it down for you in an easy-to-understand way.
Electricity for home use is generally provided by the utility company in the form of AC (alternating current). This is because AC electricity can be easily transmitted over long distances with minimal losses.
When the electricity gets to your home, it must be converted into DC (direct current) in order to be used by your device. This is where the switching power supply comes in as it can take the AC current and convert it into DC current. Learn more in our guides on house electrical AC or DC, AC vs DC power supply, and what is an AC DC power supply.
The main components of switching power supplies are usually rectifiers and transformers, but they can also include regulators and other supporting circuitry such as filters or inductors. The rectifier converts AC current from your electrical utility into DC current so it can be used by the device you're powering.
The transformer then steps down the voltage to the appropriate level needed by your device before the entire circuit is turned on and off at very high speeds (at least 10 times per second) to maintain a consistent output voltage until the current input changes again.
This type of technology has been around since the 1950s and continues to be refined with newer technologies being introduced on an ongoing basis to make these types of devices even more efficient so that you can save money on your electricity bill while still having access to quality, stable sources of energy for your needs.
When Should You Use a Switching Power Supply?
So you understand the concept of how switching power supplies work, but when should you use it?
When deciding whether or not to use a switching power supply, there are many factors to consider. A switching power supply is a type of power supply that is highly efficient and reliable in providing energy for a variety of applications. Here are some key reasons why you should consider using a switching power supply:
- Reliable Source of Energy: Switching power supplies provide a safe and efficient source of energy that is ideal for powering sensitive applications such as medical devices, home appliances, telecommunications systems, or energy-efficient lighting systems.
- Energy Saving Solution: Switching power supplies offer an energy-saving solution that can be customized with features such as over-voltage protection, allowing you to get the most out of your system and reduce your overall electricity bill.
- Wide Voltage Options: For applications that require a wide range of voltage options with stable output, switching power supplies are the ideal choice. They can handle frequent fluctuations and changes in load without compromising performance levels.
- Long Lifespan: When compared to other types of power supplies, switching power supplies have longer lifespans and often require less maintenance over their lifetime. This makes them cost-effective in the long run. Keep in mind that how long power supplies last depends on the quality of components and the power supply design.
- Easy Installation & Maintenance: Installing and maintaining switching power supplies is relatively straightforward – all you need is basic knowledge about electrical wiring and components coupled with a mechanical aptitude for putting everything together. Moreover, some suppliers also offer technical maintenance services to ensure optimal performance from your setup.
