In automobile, the introduction of electronically commutated motors has been accompanied by a proliferation of electronic devices. with this proliferation of electronic devices, an emphasis has been placed on EMC issues. This paper is proposed to use SRM as a radiator cooling fan in automotive applications To drive SRM, Energy efficient C-dump converter is applied It is verified more efficient than other converters through simulation and experiments And also SRM is valid automotive applications that have strict EMC standards. It is compared SRM with BLDC and DC motor by experiments.<br/>

In this paper, six harmonic injection PWM method for reducing total harmonic distortion in single switch three phase discontinuous conduction mode boost converter is presented In the proposed method, periodic six harmonic voltage is injected m the control circuit to vary the duty ratio of the converter switch within a line cycle so that the fifth order harmonic of the input current is reduced. Experimental results are verified by converter operating at 400V/6kW with three phase 140V-220V input.
