Application Overview
Photovoltaic energy storage systems, distributed photovoltaic power generation, and energy storage inverters operate under high voltage, wide voltage fluctuations, strong interference, and all-weather continuous operation conditions for a long time. The requirements for power conversion withstand voltage level, load driving capability, impact resistance, and long-term reliability are much higher than those for ordinary consumer grade products. The system needs to achieve photovoltaic high-voltage input voltage stabilization and reduction, battery energy storage charging and discharging management, overall power drive and circuit protection, which are the core key links in the field of industrial control and new energy.
Huaxin Er is deeply involved in the field of industrial photovoltaic energy storage and has launched a targeted 150V high-voltage synchronous voltage reduction controller, which is suitable for wide voltage input of photovoltaic panels and stable voltage conversion scenarios of energy storage battery packs. It supports high-voltage wide voltage input, efficient synchronous voltage reduction, and dynamic load regulation, and can perfectly adapt to core circuits such as MPPT maximum power tracking, energy storage auxiliary power supply, and industrial control system stable power supply. The chip has strong anti surge and anti-interference capabilities, is suitable for complex outdoor working conditions, simplifies the high-voltage power supply architecture, reduces the difficulty of whole machine research and development, and improves system stability and energy efficiency conversion rate.
At the same time, it is equipped with industrial grade high-power MOSFETs, which have ultra-high withstand voltage, ultra large current carrying capacity, extremely low conduction loss, and are suitable for energy storage high-power switch drivers, rectification circuits, and power conversion modules. It can withstand high-frequency switching and high current impact in industrial scenarios, with excellent heat dissipation performance, meeting the long-term full load continuous operation needs of energy storage equipment, effectively improving the overall load capacity and service life of the machine.
The company relies on a mature small signal product line and a continuously expanding MOSFET product matrix to serve the global industrial market with stable quality and flexible supply capabilities, providing integrated device matching for photovoltaic energy storage and industrial new energy control equipment, and creating cost-effective and highly reliable domestic solutions.
