Ozone generating power supply

Ozone sterilization by high-voltage, high-frequency power supply helps
maintain the water environment!
Ozone has a strong oxidizing power and decomposes organic substances(musty odor substances, substances that cause color, pesticides, etc.) in thewater, so it has effects such as sterilization, decolorization, and deodorization.
Ozone is generated by applying a high frequency high voltage to the discharge
tube. By developing a power source for that purpose, we are contributing to theimprovement of the water environment.

Rectifier and power inverter for stationary operation

Project scope

Tomiya City has been promoting a low-carbon hydrogen supply chain demonstration project since FY2017. in
FY2021 they added another equipment: a hydrogen co-firing generator that produces electricity by mixinghydrogen with a combination of waste cooking oil and light oil. In order to consume the electricity generated
from this hydrogen co-firing generator in-house, we supplied a rectifier and an inverter.

OutcomeThe system interconnection is not possible with the hydrogen co-firing generator alone. In order to consume
the power of the generator in-house, we introduced our rectifier and inverter, and converted the power todirect current, which enabled grid interconnection operation.
