A pulsed power transmission apparatus including: a power delivery portion configured to deliver pulsed power-supply power to a predetermined transmission line (16, 17); a filter circuit configured to reduce a harmonic component of a power-supply power waveform delivered to the transmission line (16, 17) by the power delivery portion; a switch circuit (SW1, SW2) configured to change over a function of the filter circuit between ON and OFF; and a switch control portion configured to control the switch circuit (SW1, SW2); wherein: the switch control portion is configured to turn ON the function of the filter circuit when the pulsed power-supply power is delivered to the transmission line (16, 17) by the power delivery portion, and to turn OFF the function of the filter circuit when the pulsed power-supply power is not delivered to the transmission line (16, 17) by the power delivery portion; characterized in that the power delivery portion is configured to add digital information relevant to the pulsed power-supply power to at least one of a front and a rear of the pulsed power-supply power waveform to thereby create a power packet; and the switch control portion is configured to make control to turn OFF the function of the filter circuit at a timing of delivering the digital information added to the power packet. a power delivery portion configured to deliver pulsed power-supply power to a predetermined transmission line (16, 17); a filter circuit configured to reduce a harmonic component of a power-supply power waveform delivered to the transmission line (16, 17) by the power delivery portion; a switch circuit (SW1, SW2) configured to change over a function of the filter circuit between ON and OFF; and a switch control portion configured to control the switch circuit (SW1, SW2); wherein: the switch control portion is configured to turn ON the function of the filter circuit when the pulsed power-supply power is delivered to the transmission line (16, 17) by the power delivery portion, and to turn OFF the function of the filter circuit when the pulsed power-supply power is not delivered to the transmission line (16, 17) by the power delivery portion; characterized in that the power delivery portion is configured to add digital information relevant to the pulsed power-supply power to at least one of a front and a rear of the pulsed power-supply power waveform to thereby create a power packet; and the switch control portion is configured to make control to turn OFF the function of the filter circuit at a timing of delivering the digital information added to the power packet. the switch control portion is configured to turn ON the function of the filter circuit when the pulsed power-supply power is delivered to the transmission line (16, 17) by the power delivery portion, and to turn OFF the function of the filter circuit when the pulsed power-supply power is not delivered to the transmission line (16, 17) by the power delivery portion; characterized in that the power delivery portion is configured to add digital information relevant to the pulsed power-supply power to at least one of a front and a rear of the pulsed power-supply power waveform to thereby create a power packet; and the switch control portion is configured to make control to turn OFF the function of the filter circuit at a timing of delivering the digital information added to the power packet.
