Loop Resistance Tester is a special instrument for contact resistance and loop resistance measurement of switching control equipment. The test current adopts the 100A DC recommended by China's standard GB763, and the loop resistance or contact resistance can be measured directly under 100A, 200A, 300A, 400A, 500A or 600A current. So, how does the loop resistance tester perform the synchronization and timing control of the digital power supply? The following article takes a look at this.

Usually, timing and synchronization control of power supply systems needs to be implemented using special control devices, and additional devices are needed to implement timing control, i.e. e. increases the cost and takes up space on the circuit board, timing and synchronization control is completely implemented by hardware circuits that are not adaptable and scalable, and each new product needs to be re-designed in terms of timing design and the corresponding hardware design. This is especially true for complex systems, where as many as 10 or more power rails per system may require precise timing design.

If one path of the timing design is inadvertently wrong, the entire system design can go awry. However, digital power applications make timing and synchronization control simple. the Zilker series of digital power management chips utilize a single-wire DDC bus and sync pins to enable easy synchronization and timing management between various power rails. There is no need to use special frequency synchronization signal generators and timing control devices. Only the DDC pin and sync pin of each chip are connected together via a single wire, allowing precise setting of the timing and operating phase of the corresponding device.

However, no external control is required for the operation of the chip, only the configuration file is pre-written to the chip so that the chip can achieve precise timing and synchronization phase error functions in stand-alone operation.

Loop resistance testers can easily implement timing, synchronization and error equalization functions with a configured power supply system that operates in a stable state. At the same time, with the use of digital power solutions, it is also possible to simply correct errors in a timely manner through software, without the need to spend manpower and resources to redesign complex hardware, and designers can save more time to complete the optimization of the system's processing functions, and the potential economic benefits are also great.
