[0002] Microelectronic devices, fundamental components in the electronics field, are indispensable parts of various electronic products. A large number of microelectronic devices can be connected to form integrated circuit boards. To control the operation of microelectronic devices, a regulated power supply is required. In the current technology, low dropout linear regulators (LDOs) are generally used for voltage regulation. In order to avoid power failure, emergency power supplies are used to provide backup power during power failure or power fluctuations. However, when the DC power supply experiences voltage fluctuations, it will cause the LDO to experience power supply abnormalities, thereby reducing the power supply efficiency to microelectronic devices. Furthermore, directly providing emergency power during power fluctuations will lead to a decrease in energy utilization and reduce the endurance of the emergency power supply. Therefore, improvements are needed. Summary of the Invention

The power detection module is used to sample the DC power voltage and output a sampling signal. When the sampling signal is greater than a set first threshold, it outputs a first detection signal. When the sampling signal is less than a second threshold, it outputs a second detection signal. When the sampling signal is less than a third threshold, it outputs a third detection signal and stops outputting the second detection signal. The microcontroller module, connected to the power detection module, emergency switching module, emergency power module, and switching control module, receives sampling signals. Upon receiving the first detection signal, it controls the emergency switching module to perform voltage division and high-frequency regulation of DC power and controls the emergency power module to store energy. Upon receiving the second detection signal, it controls the emergency switching module to switch the power transmission path and controls the emergency power module to discharge. Upon receiving the third detection signal, it controls the emergency power module to discharge and controls the switching control module to supply power to the voltage regulator module. Upon receiving the fourth detection signal output by the emergency power module, it outputs a charging signal. The emergency switching module is connected to the emergency power supply module. When the first detection signal is received, the DC power is divided and regulated at high frequency and the first power is output. When the second detection signal is received, the power transmission path is changed, the emergency power output by the emergency power supply module is regulated at high frequency and the DC power is compensated for voltage. The emergency power supply module is connected to the switching control module. It is used to store the DC power or first power transmitted by the switching control module, release the stored power and output emergency power, perform low power detection on the stored power, and output a fourth detection signal when the power is low. The switching control module is used to transfer emergency power to the voltage regulator module when receiving the third detection signal, and to transfer DC power to the emergency power supply module when receiving the charging signal. The microelectronic device module, connected to the voltage regulator module, is used to transmit the received operating power to the microelectronic devices.
