Impedance matching box is a part of microwave electronics. It is mainly used in transmission lines to achieve the purpose that all high-frequency microwave signals can be transmitted to the load point, and no signal will be reflected back to the source point, thus improving energy efficiency.
Impedance matching means that during energy transmission, the load impedance is required to be equal to the characteristic impedance of the transmission line. At this time, the transmission will not generate reflection, which indicates that all energy is absorbed by the load. On the contrary, there is energy loss in transmission.
Type
Change impedance force
The capacitance or inductance is connected in series with the load to increase or decrease the impedance value of the load. The points on the diagram will move along the circle representing the real resistance. If the capacitance or inductance is grounded, the point on the diagram will first rotate 180 degrees in the center of the diagram, then walk along the resistance coil, and then rotate 180 degrees in the center. Repeat the above method until the resistance value becomes 1, then the impedance force can be directly changed to zero to complete the matching.
Adjust transmission line
Lengthen the transmission line from the load point to the source point. The dot on the diagram will move counterclockwise along the center of the diagram until it reaches the circle with a resistance value of 1. Then add capacitance or inductance to adjust the resistance to zero to complete the matching.
In some computer simulation software of computational physics, such as numerical weather prediction, molecular dynamics, flight simulator, oil layer simulation method, sound barrier design, architectural acoustics and electronic circuit simulation, practical integrator is numerical methods that can be used to calculate integrals in discrete steps.
Classification
According to whether the integrator is powered, it can be divided into active integrator and passive integrator.
Active Integrator:
Active integrators are more widely used than passive integrators because they can measure a wider current range (more than 1 million amperes, less than 1 ampere) and a wider signal bandwidth (less than 0.1Hz, more than 1MHz). For Rogowski coil measuring low-frequency signals, the design of its integrator plays a decisive role in the performance of the whole test.
Passive integrator:
The passive integrator is mainly an equivalent network of resistors/capacitors. The passive integrator is only suitable for the measurement of large fast changing current pulses (large di/dt), because its performance in the low frequency part is very poor, and only when the high pulse causes the large voltage output of the coil, can it ensure that its measurement has sufficient accuracy. Therefore, passive integrators are usually used for lightning test equipment and rail gun measurement. Its only advantage is that it does not need power supply.
