In this paper the hardware implementation of producing the voltage pulses of variable duty cycle which are applied at the gate driver terminal of the switching devices used in the converter of a switched reluctance motor have been presented. These voltage gated pulses which corresponds to phase excitation sequence of the motor are necessary to run the motor. The proposed counter was tested in the laboratory with the 8/6 poles drive, and operation of the machine at variable conduction angles was found to be excellent. The implemented method of producing the variable conduction angles is simple, cheaper and easy to implement and does not require prior knowledge of programming.
