Semiconductor devices are electronic devices with conductivity between good conductors and insulators, utilizing the special electrical properties of semiconductor materials to perform specific functions. They can be used to generate, control, receive, transform, amplify signals, and convert energy.
In the excitation operation of synchronous motors, it is common to encounter the problem of parallel operation of different thyristor power bridges
There are many types of electronic products, and it is easy for overvoltage, overcurrent, or surge to occur in the circuit, which can cause damage to it. However, with the development of technology, the diversity and complexity of electronic products have led to the development of circuit protection components from the simplest fuses to various targeted and more superior protective components, such as ESD static diodes, TVS tubes, GDT discharge tubes, PPTC self-healing fuses, varistors, etc
A diode limiting circuit can cut off a portion of the signal, but it will not affect the remaining signal. Today, we will learn another diode based circuit that can lift or lower the input waveform above or below a certain DC reference level without changing the shape of the input signal waveform. This circuit is called a diode "clamp" circuit. The clamp circuit is also known as a DC restorer.
The volt ampere characteristic refers to the relationship between the voltage u applied across the diode and the current flowing through the diode, I=f（U）。 The volt ampere characteristics of 2CP12 (ordinary silicon=cathode tube) and 2AP9 (ordinary germanium diode).
