[Information] Shirutoku Report No. 67 #Method of Controlling Ballast Electricity

[Information] Shirutoku Report No. 67 #Method of Controlling Ballast Electricity

To keep the lamp lit stably, it is necessary to control the power output according to the condition of the lamp!

★★Shirutoku Report: Useful Information You Should Know★★ This report introduces the features of ballast power control. The ballast power supply refers to a device that stabilizes the discharge state of lamps, which are light sources such as car headlights and LCD projectors. Unlike general power supplies that operate under constant voltage or constant current, to keep the lamp lit stably, it is necessary to understand the lighting characteristics of each type of lamp and control the power output according to the lamp's condition. [Contents] ■ Example of lighting characteristics of ultra-high pressure mercury lamps used in LCD projectors ■ Fast control is required ■ Emits light at the necessary brightness ■ Control of the switching operation itself *For more details, please refer to the PDF document or feel free to contact us.

[Catalog] Semi-Solid Portable Power Supply GUARDIAN

[Catalog] Semi-Solid Portable Power Supply GUARDIAN

2000Wh Semi-solid lithium-ion battery adopted ultra-compact high-capacity portable power supply

Half-solid-state battery × GaN (gallium nitride) semiconductor adoption A half-solid-state battery is one in which part or all of the internal electrolyte is solid. The half-solid-state battery adopted by IDX this time is called a "liquid-addition type (impregnated type) half-solid-state battery," which uses a composite electrolyte that incorporates a small amount of liquid electrolyte into a solid electrolyte. This achieves high safety and ionic conductivity. Additionally, the internal impedance of the half-solid-state battery is reduced to 1/10 compared to conventional batteries, allowing ions to move in a space with minimal barriers (impedance), thus eliminating the need for excess energy and significantly reducing heat generation as a result. Furthermore, the inverter used inside the product employs GaN semiconductors. Compared to silicon semiconductors, GaN offers higher efficiency and faster operation, leading to improved power conversion efficiency and contributing to the miniaturization and lightweight design of the product.

Semi-solid portable power supply GUARDIAN

Semi-solid portable power supply GUARDIAN

Ultra-compact high-capacity semi-solid portable power supply

The SSP-2000 (GUARDIAN) is a portable power supply that utilizes a semi-solid battery and GaN (gallium nitride) semiconductor. A semi-solid battery is one in which part or all of the internal electrolyte is solid. The semi-solid battery adopted by IDX is called a "liquid-addition type (impregnated type) semi-solid battery," which uses a composite electrolyte that incorporates a small amount of liquid electrolyte into a solid electrolyte. This achieves high safety and ionic conductivity. Additionally, the internal impedance of the semi-solid battery is reduced to one-tenth compared to conventional batteries, allowing ions to move in a space with minimal barriers (impedance), thus requiring less energy and significantly reducing heat generation. Furthermore, the inverter used inside the product employs GaN semiconductors. Compared to silicon semiconductors, GaN is more efficient and faster, leading to improved power conversion efficiency and contributing to the miniaturization and lightweight design of the product.
