The role and characteristics of medical Inverter

Due to a variety of different types of medical equipment supply needs, use the most is the centralized power structure. I.e., by a power converter to produce the desired concentration of various voltage levels of the output voltage. Due to its low cost, high efficiency, adjustable output voltage, low output noise, fast dynamic response and other type of equipment is very suitable for medical use, is a medical device is currently Electric transformer‍ the most used type of a power supply. Medical equipment supply program to determine the need to consider the following questions.

Security and isolation is a major difference between the ordinary commercial power and medical supply. Typically, in addition to some experimental analysis class equipment, medical equipment mostly installed near the bed or the operating table, and the operator's distance from the more recent, the shell will often be touched. There are a variety of medical equipment inside the strong, weak parts, if the strength of electrical isolation between the insulated shell material or have a problem, it will be very dangerous. General medical equipment safety testing power supplies must be UL60601-1, C-UL, EN60601-1 safety certification. Inputs and outputs must be more than 4,000V isolation voltage, and low leakage current requirements to meet safety creepage distance requirements. And part of the need for a strong electric double insulation, especially some of them might be more in contact with the enclosure designed to enhance insulation.

Electromagnetic compatibility and immunity to electromagnetic interference

Select the type of equipment to be medical or AC Contactors‍ build a good power supply system must focus on improving the supply of electromagnetic compatibility and electromagnetic interference. Mainly from the following aspects to consider: design. PCB design and layout, in general will contain some of the high frequency power signal, any traces on the PCB can be functioned as an antenna, the length and width of the printed lines will affect the resistance and inductance, thus affecting the frequency respond in a timely manner will be coupled to the RF signal and cause problems through the circuit traces DC signal from adjacent tracks. Medical power supply must be selected so that the big brands, has a strong R & D strength of the company's products, which in the design and production processes can ensure good quality.

Shield

In order to suppress the switching power supply generated by radiation, eliminate the influence of electromagnetic interference from other electronic devices in the medical equipment, the best way is to supply the magnetic shield, the shield and then the entire cabinet or medical devices to a single entity, this is a more effective approach.

Authenticate

General medical device class stage power needs through FCC-B, CISPR22-B, EN55011550226120461000 such as electromagnetic compatibility and immunity to electromagnetic interference testing. Select the completion of these tests not only within the right equipment to ensure the electromagnetic influence Power Transformer‍ other electronic components, and medical equipment can reduce development cycles and time to market prior to the subjects.
