APPLICATION THE INVERTERS IN DEVICES OF NUCLEAR MAGNETIC RESONANCE

Abstract

Expediency of generating the PWM pulses and further filtering to obtain probing Khan current in emitter NMR device is shown. The basic topology converters for generating a probing voltage in nuclear magnetic resonance devices are discussed. Shown their advantages and disadvantages. It is illustrated that the use of a single coefficient estimates non-sinusoidal waveforms does not provide complete information about the resulting voltage. Proposed new coefficients for analysis Khan signal. Using the simulation results and calculation, it is concluded that the most appropriate use of multilevel converters for voltage probing devices NMR . Concluded that further increase the number of levels the multilevel inverter will increase the accuracy of the formation the probing current, but will complicate the NMR device.
