The term “power supply” refers to the source of electricity. The majority of electronic circuits need a DC power source. Most likely, you already have one at home that you can use for physical computing projects.

The power supply is a very common component of electronic test equipment since it may be used in various testing scenarios. Although the term “power supply” may be used to refer to anything that generates electricity, such as a combustion engine, we’ll restrict our discussion to the several types of direct current (DC) power sources frequently employed for design, upkeep, measurement, and testing.

By now, you should be aware that a DC Power source produces a steady DC voltage. Their primary energy source is AC mains power. However, depending on how it is designed, its power supply may be either a DC or AC source. There are several DC Power supply types as a result. Different types of DC power supplies include:

• Constant voltage/constant current power supply
• Multiple output power supplies.
• Programmable power supplies 

To further understand what a DC power supply is, let’s take a closer look at each of these many varieties.

Constant Voltage/Current

The most common type of power supply is probably the constant voltage/constant current power supply, which, as its name suggests, offers both constant voltage and constant current. These power supplies retain their set current when in constant current mode, regardless of changes in the load resistance. Constant voltage/current power supply commonly contains features like remote sensing, master/slave connections, and analog programming (remote programming terminals.)

Multiple Output

Power supply with multiple outputs often has two or three outputs. A multiple-output power supply is the most economical option if you discover that you frequently utilize different voltages when testing. A triple-output power supply is popular because it offers two outputs for bipolar analog circuits and one for digital logic. Common characteristics include the ability to connect two channels in parallel or series for larger current or voltage, settable voltage constraints, storage registers for up to fifty instrument states, and scheduled operation.

Benefits of DC Power Distribution in Buildings

• Eliminate the Need for Inefficient Power Converters

A growing variety of contemporary appliances uses DC power, such as LED lighting, HVAC systems, computers, microwaves, etc. In reality, DC consumption presently accounts for around 32% of all energy loads and may reach 74% in buildings with electric car charging stations and HVAC systems with DC motors. Currently, houses and buildings receive electricity from AC power networks, meaning these devices must change the AC power into the DC power they require.

• Essential for Smart Buildings to Work Efficiently

As was already noted, most modern systems and equipment need DC energy, and smart homes and buildings are no exception. DC energy is used to power all gadgets required for smart buildings, including sensors, cameras, LED lighting, and other components. More energy-efficient structures are created with smart technology. For instance, they frequently gather information on a space’s occupancy and environmental condition to optimize energy consumption. However, energy is still lost if high energy-consumption equipment, such as LED lights and HVAC, still needs to convert AC to DC.

• DC Electricity is Safer to Handle

Whether you’re working with AC or DC electricity, it’s never perfectly safe. So always take precautions. Alternatively, getting in touch with a professional is safer if you’re unsure what to do. That being said, while both are dangerous, AC electricity is more dangerous to work with due to these reasons: 

• Humans can handle higher volts of DC energy than AC because their bodies are more resistant to DC currents than AC. In layman’s terms, the technical explanation is that AC power generates an alternating magnetic field that may pass through insulators.
• According to experiments, live components may be released more easily in a DC circuit than in an AC circuit. Naturally, you can release the source of shock, which makes it simpler to restrict exposure to dangerous voltages.
• Even if DC power were to get through our skin, AC electricity would be more dangerous. This is because, in the event of an electric shock, DC electricity might instead produce a cardiac standstill (owing to ventricular fibrillation). In contrast, alternating behavior like AC drives the heart’s pacemaker neurons into atrial fibrillation.
• Many DC Powered Devices are Intrinsically Efficient

When compared to incandescent lighting that AC drives, LED lights are an excellent example of a DC-powered product that is energy efficient. Building management would be more motivated to integrate energy-efficient DC-powered equipment into their building systems if their structure was powered by DC electricity. For instance, if a building has an HVAC system with an AC motor, the building owner may replace it with a DC motor since it is more efficient. This switch saves substantial energy because DC HVAC motors are at least 50% more efficient than AC motors. Increased use of DC power distribution networks encourages the development of new building efficiency-boosting DC-powered technology.
