Nichicon Co., Ltd. has added a 600V rating to the small-sized aluminum electrolytic capacitors of the "LGN series" self-standing 105 ° C substrate used in various industrial equipment, such as high-voltage inverter circuits for power electronics systems. Mass production, promoting this product to renewable energy related fields.

This product will be exhibited at “CEATE JAPAN 2016” held at Makuhari Messe International Exhibition Center (MAKUHARI MESSE) from October 4 (Tuesday) to October 7 (Friday)

Overview / development background

With the deepening of efficiency and energy saving in the industrial equipment field, the high voltage of power systems is also being promoted, and the high withstand voltage requirements for aluminum electrolytic capacitors used in control circuits such as inverter circuits are increasing. In particular, the requirements for renewable energy related fields such as solar power generation and wind power generation are higher. Previously, the "LGN series" substrate self-supporting 105 ° C guarantee that the maximum rating of small aluminum electrolytic capacitors is 500V. This time, the industry's highest 600V rating has been added. This is a comprehensive and product line, and it is the most suitable for power electronics equipment that emphasizes energy efficiency. Recommend strongly.

Specialty

The 600V rating of the "LGN Series" is achieved through the use of electrolytes and high-voltage-resistant electrolytic paper that have long-term stability and high-voltage-recovery capabilities at high voltages, such as highly reliable electrode foils with high-voltage-resistant oxide films. Voltage. In particular, the composition of the electrolyte was optimized to increase the high withstand voltage by about 20 to 30%, and a new electrolyte with a high withstand voltage of 100 ° C and 600V was newly developed.

The rated voltage is higher than existing products, and it is being strongly promoted to power conditioners for large-scale solar power generation systems. Due to the high circuit voltage, multiple aluminum electrolytic capacitors are connected in series. However, by using the 600V rated "LGN series", the number of pieces can be reduced. For example, for a voltage of 1,200V, a 400V product requires three series connections, but a new 600V product requires only two series connections, which can be considered as a space-saving circuit design.
