How auxiliary power supply is designed for high-voltage and wide-range input?
Aiming at the problems of switching stress, cost and efficiency caused by high-voltage and wide-range input, the principle analysis and parameter design were carried out based on the series-connected MOSFETs flyback converter, and a 100W auxiliary power supply prototype with 300-1500V input and 24V output was designed.
What is auxiliary power supply?
Abstract: As an important part of power conversion device, auxiliary power supply is faced with the application demand of high-voltage and wide-range in solar power station and other systems.
Is auxiliary power supply a low-cost wide input range & high stress power conversion?

As an important part of power conversion device, auxiliary power supply is faced with the application demand of high-voltage and wide-range in solar power station and other systems.
Why do we need energy storage systems?
As a consequence, the electrical grid sees much higher power variability than in the past, challenging its frequency and voltage regulation. Energy storage systems will be fundamental for ensuring the energy supply and the voltage power quality to customers.
How does a high voltage high-frequency plasma switching power supply work?
The inverter, which is in the front stage of the APS, converts the DC voltage into an AC voltage, and the output side of the inverter is connected to the voltage bus. A high voltage high-frequency plasma switching power supply was presented in [ 17 ].
Can auxiliary power supply maintain a stable operation under open-circuit conditions?
It can be seen that the auxiliary power supply has no self-regulation characteristics, and the output voltage cannot be stabilized within the input voltage range of the voltage regulator circuit. Finally, the APS cannot maintain stable operations. Figure 7 b shows the simulation results of the parameter-optimized APS under open-circuit conditions.
