Title:
AUXILIARY POWER SOURCE FOR ENERGY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/044999
Kind Code:
A1
Abstract:
An auxiliary power source for an energy storage system. The auxiliary power source comprises: a resonant circuit module (110), comprising a first power supply input end (IN1), a second power supply input end (IN2), a first power supply output end (OUT1) and a second power supply output end (OUT2), wherein the resonant circuit module (110) operates in an open-loop mode, and converts a direct-current bus voltage into a secondary output voltage; and a flyback power source module (120), comprising a third power supply input end (IN3), a fourth power supply input end (IN4), a fifth power supply input end (IN5), a sixth power supply input end (IN6) and a power supply output end (VOUT), wherein the flyback power source module (120) operates in a closed-loop operating mode, and converts the voltage of an energy storage battery (130) and/or the secondary output voltage of the resonant circuit module (110) into an auxiliary power source output voltage.
