Most of the AC power supplies on the market are AC constant voltage sources, in some specific test scenarios, such as for current sensors, current transformers, wiring harnesses, connectors, circuit breakers, low-voltage appliances and other products will need to use the AC constant current source, AC constant current source can be set according to the value of the current and the frequency of a certain voltage range within the output in order to verify the accuracy of the current or current-carrying capacity.

New energy vehicle sales continued to grow strongly in 2023, a year in which major automakers not only made significant breakthroughs in powertrain and battery technology, but also explored in-depth intelligence and internet connectivity.

Background Nowadays, the competition of practical use of solid-state batteries has begun. Toyota, which is leading the way in patents, plans to open trial production EVs within 2021. Volkswagen and Quantum Scape, a Silicon Valley start-up, will start producing batteries that can significantly extend the range of PEV around 2024. Solid-state battery technology is regarded as the next-generation key technology affecting the EV industry.

In new energy vehicles, the motor and power battery are undoubtedly key components, but there is another key device that is easily overlooked - the inverter. Whether it's in models equipped with permanent magnet synchronous motors or three-phase asynchronous motors, the inverter exists as a key component. The reason why the inverter is so important is that the power battery outputs DC power, which must be converted when supplying power to the AC motor.

With the rapid development of microelectronics technology and the improvement of the design level, the integration degree of the chip and the amount of computing data increases significantly, which leads to a sharp increase in the power consumption of the chip.

Solar power systems rely on solar panels to generate electricity, however the inverter is what converts this DC power into usable AC power. The traditional way of generating electricity is to connect the solar panels directly in series, and then connect them to a string inverter, which is connected to the power grid for use by other devices.
