ABSTRACT: In
medical diagnostics, therapeutic, laboratory, intensive care unit devices, and
machines application, two form of Electrical Energy is utilized. Alternatives
current (AC) and Direct current (DC) form. In this paper an inverter driver system with a display
model is made using MATLAB and its specific tool box of Simulink, the process
will involve converting single phase alternating current power to direct
current using rectifier made from ordinary normal diodes then converted to three phase using three-arm insulated gate
bipolar transistors this is commonly known as inverter bridge which is
sufficient enough to run three phase loads depending on the application
requirement. The system uses a five-level inverter with low levels of
distortions and ripples in the equipment output, this increase and improves the
performance of the system. Using carefully selected passive and active elements
such as capacitor resistors, inductors, diodes, and transistor system in
inverter, decreases the number of switches and boosts the efficiency of the
system. This inverter drive system helps us to run three phase machines in the
health facility at the same frequency of
single phase. The inverter system allows a smaller smoothing capacitor in the
DC-AC link as proposed. Large smoothing capacitors are conventionally essential
in such converters to absorb power ripple at twice the frequency of the
power supply. The proposed network topology consists of an indirect matrix
converter and an active snubber to absorb the power ripple, and does not
necessitate a reactor or large smoothing capacitor. Simulation result is shown
using MATLAB software and used to verify system operation principle as well as
circuit development and their control mechanism for a single-to-three-phase power inverter system. The results from experiment show that for a 1 kW-class prototype circuit system, the power ripple at
twice the frequency of the power supply can be adequately suppressed using a
buffer capacitor of low values.
