S1GL RVG

Single-Phase Glowing Rectifier Tube

S1GL (Single-Phase Glowing) Rectifiers are an energy-conversion device that utilises the thermionic emission of electrons from a heated cathode to form what is known as a rectifying tube. It is typically used in electrical power supplies and other high voltage or large current circuits, as a protective and regulating device. This article will discuss the application field of the S1GL Rectification Tube and its working principle.

Application Field

The application field of the S1GL Rectification Tube includes applications in high-voltage DC power supplies, electric traction systems, industrial automation and motion control systems, welding equipment, generator systems, and power metering and control systems. This device is particularly suited to applications that require high levels of current, such as electric preheating and induction heating.

The S1GL rectification tube is also often used in conjunction with an LC filter, in order to further smooth the output voltage and reduce the ripple. This can be used in applications requiring reliable operation over long periods of time, such as automotive applications, as it reduces the power loss and improves the lifetime of the circuit. The S1GL rectification tube also has a low self-heating coefficient, making it suitable for low-temperature operation.

Working Principle

The S1GL Rectification Tube works by utilising thermionic emission of electrons from a heated cathode. A heated cathode emits electrons when it is heated to a certain temperature, known as the cathode temperature. This connection of cathode to anode generates a low-level current in the device, which is then amplified by a vacuum tube triode. This triode is responsible for amplifying the AC input signal, while a rectifying diode connects the anode to the output of the device.

The anode forms the output side of the S1GL Rectification Tube and is connected to the load circuit. The rectifying diode takes care of forming a flow of current from the anode to the finishing point and also removes the AC components from the output signal. When the device is in operation, the electron transfer from the heated cathode to the anode forms a low-level current, and the positive and negative currents through the anode and cathode respectively are balanced thereby. This balanced condition continues until the AC component of the output is completely eliminated.

Conclusion

In conclusion, the S1GL Rectification Tube is a useful device that is typically used in high-voltage electrical power supplies and other high current circuits as a protective and regulatory device. This device relies on thermionic emission of electrons from a heated cathode in order to form a rectifier tube. The S1GL is suitable for a range of applications, including applications in electric traction systems, industrial automation and motion control systems, welding equipment and power metering and control systems.
