How to choose a good medical power supply?

2024-06-24

Power supply is the heart of medical equipment energy. Its basic performance and potential application risks have a vital impact on the entire medical equipment. The first question for medical equipment manufacturers is, should they make their own or outsourced power supply? Frankly speaking, it is not difficult to design a power supply, but it is not easy to design and produce a high-quality medical power supply. Therefore, it is more cost-effective for medical equipment manufacturers to directly purchase a good medical power supply and free up their energy to focus on their own profession. So, what factors need to be considered in order to choose a good medical power supply?

Application Of Saturated Inductor In Switching Power Supply

2023-09-20

The saturation inductor is an inductor with a high hysteresis loop rectangular ratio, high initial magnetic permeability, small coercive force, and an obvious magnetic saturation point. It is often used as a controllable delay switching element in electronic circuits. Due to its unique physical properties, it has been increasingly widely used in switching noise suppression of high-frequency switching power supplies, voltage stabilization of high-current output auxiliary circuits, phase-shifted full-bridge converters, resonant converters and inverter power supplies.

Fly back Synchronous Rectification Problems and Countermeasures

2023-04-05

In recent years, with the continuous improvement of international energy efficiency standards, conventional Schottky diode rectifiers cannot meet the energy efficiency requirements of low-voltage and high-current output specifications (DoE Level VI in the United States, CoC V5 Tier 2 in the European Union); even with ultra-low Vf Xiao For the rectification of special base diodes, some heat sinks need to be added, which will lead to large PCB space, low power density, low efficiency, high shell temperature, and poor user experience.

Safety distance requirements

2022-11-17

In the standard of GB4943, the minimum safety distance required according to different working voltage levels is specified, and the safety distance specifies two types of creepage distance and electrical clearance. For the switching power supply, there are the following two aspects where the minimum safety distance needs to be guaranteed.

Management application of medical power supply in various fields--Patient Monitoring

2022-07-01

Such systems are all clinical systems. They are used to measure blood pressure, but can also be used in electrocardiogram (ECG) and pulse oximeter systems. This type of power management usually uses line power, so as long as heat dissipation can be handled well, energy efficiency is not a big issue. What is really important is reliability, galvanic isolation for safety purposes, and low noise. To increase reliability, backup batteries are sometimes provided.
