Solar power generation has become one of the most important renewable energy sources on Earth, but have you ever thought about what would happen if we could collect solar energy in space? In space, there is no atmosphere to block the sunlight, and with no day-night cycle, solar radiation can be received continuously for 24 … Read more
Level ShiftersLevel shifters – converting voltage from low to high Driving logic signals from a low power rail to a high voltage rail is a critical issue. Under-driven signals can lead to degraded rise and fall times at the receiving end. This, in turn, can result in higher switching short-circuit currents and reduced noise margins. … Read more
After years of low-power hardware design (the hardware and software design in the company are separate, and I have always worked on hardware, often facing the challenges of low-power production incidents), one common issue is that the IO configuration is not set correctly before the microcontroller enters sleep mode. The main problems with the product … Read more
Industrial automation equipment is usually not associated with “low power consumption”; however, in special scenarios such as remote monitoring stations and mobile devices, enabling the S7-1200 to enter “energy-saving mode” becomes necessary. This is akin to modifying a family sedan into an off-road vehicle, requiring a series of professional modifications, but it is absolutely feasible. … Read more
