What is the arch converter?

The arch converter is a device that receives electricity and generates sound or radio frequency energy. It uses an electric arc between two wires that are part of the electrical circuit, and requires the initial high voltage for generating an arc and a stable current to maintain the arc. The generated arch contains a wide range of frequencies and can be tuned to a specific frequency using an electric tuned circuit. It is also referred to as Poulsen Arc after its inventors and also known as the Arc transmitter. The arc per inch (2.54 cm) gap takes about 70,000 volts (V). Once the arch is lowered and temperature accumulations at the ends of the wires, there is a permanent arch. To ensure that the ends of the conductors are not melted because the temperatures of these ends can achieve melting the conductive metals such as copper.

radio frequency AC current (AC) was first createdby means of an electric arc and a resonant circuit. Generating the radio frequency from the converter of the arch relies on the presence of the arched of the tuned circuit through the arch. This tuned circuit is a conductor with inductive and capacitive characteristics that are distributed and results in a parallel resonant frequency where reactive properties are disturbing each other, causing a sharp reduction in clean current through the tuned circuit. The result of parallel resonance is the condition seemingly disconnected from the arch at a certain frequency. The only energy of an arc that can exist with the arch converter is the energy on the parallel resonant frequency of the tuned circuit.

Resonance or tuned circuit in the range of radio frequency is usually less than a single turn wire with a diameter of about 12 inches (30.5 cm). This wire becomes an antenna loop that has distributed capacity and induction characteristics. Frequency higher output requires a smaller loop diameter, while frequency with lower output youIt lines a larger loop diameter. While capacitive characteristics are brought by capacity formation due to the close adverseness of two wires separated by insulator, which can host a considerable amount of electrical field intensity, inductive properties bring the accumulation of the magnetic field around the conductor that tends to further change the current through the conductor. In Early Wireless Communications, the power supply power supply (DC) with the arch converter was the only available radio transmitter.
