In any hospital or medical setting, it is essential that power supplies are reliable and safe. A power outage or malfunction can be dangerous for both patients and operators. In this blog post, we will discuss the importance of power supplies for medical use, and some of the safety features that could occur if you don't choose a medical approved power supply.

The main difference between a switch mode power supply and a regulated power supply is that the former uses switches to control the flow of energy, while the latter uses linear regulators. This means that switch mode power supplies are more efficient than regulated power supplies, since they don't have to convert all of the incoming energy into heat. However, switch mode power supplies can generate more noise than regulated power supplies, so it's important to choose the right type of power supply for your application.

Renewable energy is defined as energy that is derived from renewable resources that are renewed naturally on a human timescale and may be harvested. It encompasses a variety of energy sources such as solar, wind, tides, waves, and geothermal etc. To cover requirements of renewable energy, the IEA predicts that renewable energy will account for over 30% of global power generation by 2030, with solar PV accounting for 10%. Over 50% (solar PV: 20%) by 2040, and over 80% (solar PV: 60%) by the end of this century.

Industry commentators point to the 2020s as being the decade for Industry 4.0 to really take hold. In multiple sectors of the economy, large strides in technology are changing the way businesses operate and how we live: moving towards an Internet of Things approach where Machine-to-Machine communication facilitates complex and reactive pipelines.
This “fourth Industrial revolution” is taking its hold in the agricultural sector too: with one tool driving this change and providing a generational leap in farming efficiency for those with the foresight to buy in: the industrial unmanned aerial vehicle (UAV)… or more commonly known as the drone.

Medical devices (patient contact devices) need to have means of patient protection (MOPP). For a 1xMOOP, power components must have an isolation of 3000Vac, a creepage of 4mm and basic insulation. If the system requires a 2xMOPP, this is the most stringent standard so far: with an isolation of 4000Vac, a creepage of 8mm and double insulation. It is a 2xMOPP compliance that provides the highest level of safety in a medical device.
If you’re opting for an AC/DC power supply that adheres to only 1xMOPP, introducing a DC/DC converter meeting 1xMOPP can help you gain two means of patient protection. However, most system designers in the medical industry prefer to ensure that all power components reach the necessary standards instead of ‘doubling up’ to increase safety.

Most standard power supplies are controlled by analogue signals from passive components. Even the most sophisticated power systems have an extremely limited pathway for configuring and monitoring crucial parameters like fault data and adjusting output voltage.
But as the industry has developed greater need for power systems with greater accuracy and precision control in key adjustable operating parameters, many system designers have turned to digital controlled power supplies for on-the-fly monitoring and management of their crucial power systems.

Whilst standard industry-grade power supplies are great for commercial and industrial workloads, when it comes to defence appliances, there exists a whole host of different requirements to meet the standards for use in the military.
Defence applications are one of the most demanding scenarios for power appliances, combining the high DC output needed to drive complex machinery with extreme endurance and ruggedisation to increase the safety and longevity of devices.

When do I need a high voltage power supply?
A high voltage power supply is a power conversion circuit that converts a low potential difference input to a high potential difference. With an AC current, it’s fairly simple to variate voltage levels via a transformer, but this isn’t the case for DC power.
In the past, there was little need for high voltage applications, with low voltage 12V/24V/48V industrial power supplies being the norm. However, nowadays, as industrial applications become more and more demanding, the demand for high voltage outputs has grown accordingly. Whilst many companies have opted to research and develop their own bespoke DC-DC solutions, the astronomical cost involved in designing industrial power supplies makes this option off-limits to smaller firms and users.

Over time, safety and environmental standards have been changed for the benefit of all in the medical industry. Here at Components Bureau we can help you decide on the most efficient power choice for your application.
Medical power supplies are used in multiple medical equipment applications including MRI, X-ray, CT and PET scanners, DNA equipment, ultrasound, diagnostic equipment and automated pharmaceutical dispensers.
There is a trend for all medical equipment to make them compact, light-weight and efficient.
All medical equipment has to meet a set of safety standards that keep the patient and the operator safe.

For any complex, sensitive or critical application; configurable and modular supplies can play a vital role in the overall system and can provide greater flexibility for the overall design. Modular and configurable power supplies provide a vast array of outputs using commercial, off the shelf building blocks, delivering a custom solution from proven, standard, stocked modules. Custom designs can be delivered in days rather than weeks or months.
