In the era of information, the demand for power supply reliability is higher than ever. This is especially true in critical applications such as data centers and communication base stations, where power stability directly impacts the normal operation of the entire system.

The development of automotive electrical and electronic systems has evolved from simplicity to complexity. Early vehicles were equipped with basic circuits for ignition and lighting. In the mid-20th century, with the rise of semiconductor technology, voltage regulators and transistor ignition systems were gradually adopted. After the 1980s, the microprocessor revolution drove the widespread use of electronic control units (ECUs), enabling the digital control of core components such as engines and transmissions. In the 21st century, the development of in-vehicle network architectures and intelligent sensors made distributed electronic systems possible, leading to the emergence of 48V mild hybrid systems and high-voltage electrical platforms. Currently, automotive electrical and electronic systems are evolving toward domain controller architectures, supporting advanced driver-assistance systems (ADAS) and connected vehicle functions. Their complexity has surpassed that of traditional mechanical systems, becoming the technological core of modern vehicles.

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.

With the rapid development of new energy vehicles and low-altitude economy technologies, hybrid energy systems combining lithium batteries and fuel cells—known as hydrogen-electric hybrid systems—are emerging as a key solution to enhance energy efficiency and extend operational endurance.
