随着科学技术的飞速发展,各种各样的新型医疗设备层出不穷,为人们的健康保驾护航。不论设备功能多么先进、复杂,有一样东西是别不可少的,那就是电源,它是整个设备能量转换的动力源。尽管各种设备的原理不尽相同,但其电源的原理却大同小异。医疗设备中通常采用开关电源。开关电源具有功耗小、效率高的特点。在开关电源中,晶体管在激励信号的激励下,
With the rapid development of science and technology, a variety of new medical equipment emerge in an endless stream to protect people’s health. No matter how advanced and complex the equipment is, there is one thing that is indispensable. That is the power supply, which is the power source for energy conversion of the entire equipment. Although the principle of various devices are not the same, but the power principle is more or less the same. Medical equipment is usually used in switching power supply. Switching power supply with small power consumption, high efficiency. In the switching power supply, the transistor excitation signal,
