Newbie level 6
In the new energy era, the rapid growth of energy systems has driven the rapid development of energy storage systems.
In energy storage systems, the power and response speed requirements of key components (such as inverters, converters, battery management systems, etc.) are constantly increasing, which poses a more severe challenge to electronic components. Capacitors with better performance, higher capacity density and strong stability are needed to support energy storage systems to maintain excellent stability and reliability in various environments.
PART.01 Energy storage inverter
The role of the inverter in the energy storage system is mainly energy conversion, control and communication, power control, etc. It mainly uses capacitors with high capacitance density, high ripple current resistance and high voltage resistance to play the role of voltage stabilization and filtering, energy storage and release, and smooth DC pulsation.
YMIN capacitors have the following characteristics in the inverter:
Advantages of high capacity density:
At the input end of the micro-inverter, it is necessary to receive the electric energy generated by the renewable energy device. These charges need to be converted by the inverter in a short time. The characteristics of YMIN capacitors with high capacity density can carry more charges in the same volume, absorb part of the electric energy, improve the conversion efficiency, and realize the conversion from DC to AC.
High ripple current resistance:
When the inverter is working, the current generated at its output end may contain a large amount of harmonic components, which will have an adverse effect on the power grid consumption end. YMIN filter capacitors can effectively reduce the harmonic content at the output end and meet the load's demand for high-quality AC power.
Advantages of high withstand voltage:
Due to the unstable voltage of photovoltaic output, the power semiconductor devices in the inverter will also generate voltage and current spikes during the switching process. YMIN capacitors have the advantage of high withstand voltage, which can absorb these spikes, protect power devices, make the voltage and current changes smoother, reduce energy loss, and improve the efficiency of the inverter.

The ultra-high withstand voltage characteristics of YMIN capacitors can be used as protection components to protect sensitive electronic components from damage when voltage spikes are generated during the operation of the converter, so that the energy storage converter can provide stable voltage and frequency support for the grid and ensure the stable operation of the system.
Large capacity:
YMIN capacitors can store electrical energy and supply continuous electrical energy to the converter system when the grid voltage fluctuates greatly or when the power is cut off, ensuring the normal operation of the converter system. In inductive loads such as motors, capacitors can also provide reactive power compensation, stabilize voltage, and improve the output performance of the motor.

When the load in the battery management system requires a large current instantly, YMIN capacitors can quickly release the stored energy to meet the instantaneous needs of the load. It can be used as a protection circuit to provide short-term power support for key circuits, ensure that the protection circuit can work normally, and cut off the connection between the battery and the load in time.
