This paper presents an investigation of PWM control with plasma synthetic jet actuator (PSJA). PSJA is an electric device designed for flow control using electrohydroninamic (EHD) effect. PWM control (ON-OFF control to glow discharge periodically) was proposed to induct waves which are subjected to lower frequencies than the frequency to drive the PSJA. The results show that the decrease of drag such as maximum velocity deficit and RMS has dropped by selecting a proper frequency in an angle of attack 15°, where the decrease of drag wasn't observed without PWM control. The result has indicated that the most effective frequency exists for separation control with PWM.
