Impedance Connection Matching of Baluns and RF Components

Impedance mismatches in the circuit cause energy to reflect back to the source, reducing the amount of power available to the load and potentially damaging the source. Matching the output impedance of the power supply to the input impedance of the power supply to the input impedance of the electrical load maximizes the reflected energy […]

Maintenance method of led light flickering

What are the maintenance methods for the flickering led lights? The reason why the LED light keeps flickering is probably the power loss problem inside the appearance of the LED. Another possibility is that the LED has the phenomenon of electro-optical decay. The flickering also exacerbates their ever-rising temperature. The maintenance method of the LED […]

Talking about RF Transformers and RF Transformer Types

When the signal current flows through the primary coil, a magnetic field is generated, which in turn generates a voltage on the secondary coil. When there is a load on the secondary coil, there is current flowing through the load, that is, power is obtained. This is how a transformer works. Today, let’s talk about […]

Talking about Vicor Non-isolated Bidirectional Bus Converter Module

Traditionally, in distributed architectures, bus converters provide an isolated intermediate bus voltage that powers various point-of-load (POL) regulators on the system board. This architecture is common in many applications, including ATE, servers, telecom systems, and industrial controls. While there are many advantages to using an isolated bus converter, there are also some disadvantages. In addition […]
