Abstract

In current times, finding medical equipment which does not use a switched-mode power supply (SMPS) or any other solution of this kind is very hard. This paper presents the electronic design of a SMPS with nickel-metal hydride (Ni-MH) battery backup, which is devised to be used in a group of portable ECG machines developed in Cuba. After obtaining the general diagrams of this power supply, the three main blocks are briefly explained. Then, the different parametric and electric security tests carried out in each of these blocks are talked about. The results of these tests prove that the development of the required SMPS for the medical equipment produced in Cuba is thoroughly feasible. © Springer-Verlag Berlin Heidelberg 2007.
