Most articles on IoT devices focus on the abstract mechanisms of big data and the AI algorithms that operate them. However, there are more rudimentary aspects that are also very important. The power supply plays a more integral role than many people expect.
IoT for All discusses this reality in one of their pieces. They covered the importance of SMPs in ensuring IoTs have a robust power source.
SMPs Are Essential for the Operation of Modern IoT Devices and Networks
The growing popularity of IoT devices has been an evolving story over the last decade. There are now around thirty billion IoT devices in the world today. These devices collect data which businesses can leverage in countless ways. You’ll find IoT devices in everything from railway systems to automobiles to industrial specialized hardware.
Each of these devices can only do this job reliably if they are provided with a stable source of constant power. However, they wouldn’t be able to reach their full potential without the support of SMP power supplies.
What Are the Benefits of SMPs?
IoT networks need a steady supply of power. This job is typically performed via a Switched Mode Power Supply (SMPS), of which there are a wide range on offer at stores.
The market for SMPs is growing at a surprising pace in regions all over the world. By 2026, the market for power supplies of this type is expected to swell to $1.8 billion, rising at a compound annual growth rate of 4.3%. During this period, devices are only expected to get smaller and more lightweight. While the death of Moore’s Law might have confidently predicted, we might still expect manufacturers to push toward smaller sizes in devices of every kind.
These devices hold several key advantages over the traditional linear supplies.
Switching power supplies spends its time in either a full-on or full-off state, which minimizes dissipation. This leads to efficiencies leading upwards toward 90%. Greater efficiently is inherently a good thing. But it also lessens the impact of a given device on the climate, which is a concern felt more keenly than ever by both consumers, politicians, and industry leaders.
Moreover, supplies of this kind are able to operate at a broad range of switching frequencies, which allows them to be integrated more easily into different products. This is important, because different devices access IoT networks at different frequencies.
In safety-critical applications like railway signaling and industrial machines, it’s especially important for the power supply to provide a robust stream of current. Switching supplies have proven themselves in real-world applications, and are trusted by industry.
While the circuitry involved is more complex than in a linear supply, it can also be crammed into a smaller space, and it weighs much less. These are qualities which come in incredibly useful in IoT devices, which often need to be made extremely small.
What About Covid-19?
Coronavirus has disrupted global supply chains and put a major dent in certain industries, like the automotive industry. On the other hand, demand for computers and computing-related products has skyrocketed. With more of us working from home than ever before, and relying on teleconferencing software in order to do so, demand for high-quality webcams has soared. Other devices, like electronic thermometers and other health-monitoring hardware, have received a boost from the pandemic. For DC/DC in particular, demand continues to steadily escalate.
In other words, the effects of the disruption, positive and negative, have tended to even one another out over time – though this may change going forward.
