The article concern with the study of transformers especially single phase transformers through efficiency assessment parameters with ohmic load for automatic control and regulation of quality indicators using electrical devices and controllers. As a result of the experiments, it was revealed that a single-phase transformer and simulation of wave parameters in secondary voltage observed with a help of  changing in the different Voltage  parameters. The simulation allows you to control the electrical devices through a controllers, by simulating the signals of primary and secondary coils; you can control and monitor the transformer parameters when the AC to DC converters circuit and automatic control in every electrical devices.
