Abstract (en)
[origin: EP0849978A2] The device In a circulation chamber of the fluid to be warmed surrounded on the outside by an inductor circuit that magnetically shorts circuits. The inductive charge is fed by a power stage, and other power components, driven by modular drivers which in turn are controlled by a microprocessor with two specific aims, to generate the square wave at the established frequency, which controls the power stage, by means of the drivers, as well as to control the system's functions of heating. <IMAGE>
