How does the loop resistance tester perform the synchronization and timing control of the digital power supply?

Release time:


The loop resistance tester is a special instrument used to measure the contact resistance and loop resistance of switch control equipment. The test current adopts 100A DC recommended by my country's standard GB763. It can be directly used in the case of 100A, 200A, 300A, 400A, 500A or 600A. Measure loop resistance or contact resistance. So, how does the loop resistance tester perform the synchronization and timing control of the digital power supply? Let's take everyone to discuss it together.

Usually, the timing and synchronization control of the power supply system needs to be realized by special control devices, and additional devices are needed to realize the timing control, that is, e. increases the cost, and also needs to occupy the space on the circuit board. The timing and synchronization control are completely controlled by Without adaptability and scalability of hardware circuit implementation, each new product needs to be redesigned in timing design and corresponding hardware design. Especially for complex systems, there may be as many as 10 or more power rails in each system that require precise timing design.

If one path of the timing design is accidentally wrong, problems will occur in the entire system design. However, the application of digital power makes the timing and synchronization control extremely simple. The Zilker series of digital power management chips utilize the single-wire DDC bus and sync pins to easily achieve synchronization and timing management between various power rails. No need to use special frequency synchronization signal generator and timing control device. Only the DDC pin and sync pin of each chip are connected together by a single wire, and the timing and working phase of the corresponding device can be accurately set.

However, the chip does not need external control when it is running, and only needs to write the configuration file into the chip in advance, so that the chip can achieve precise timing and synchronization phase error functions when running independently.

The loop resistance tester can easily realize the functions of timing, synchronization and error equalization through the configured power supply system, and the working state is stable. At the same time, after using the digital power solution, errors can be corrected in time and simply through software, without the need to spend manpower and material resources to redesign complex hardware. Designers can also save more time to complete the optimization of system processing functions, which is potentially economical. The benefits are also great.
