Power Electronics
Power electronics is the technology used to convert the power obtained from a power plant or renewable energy source into a usable form for end users. Substation equipment and EV drive systems are also made possible by power electronics technologies. Substation equipment is essential for a stable power supply. EV drive systems convert electrical energy stored in batteries into the power that drives EVs. This page looks at some examples of power conversion technology and EV drive system design technology.
DC power distribution systems
Solid-state transformers (SSTs)
- Multiple, interconnected AC/DC conversion modules built into a high-frequency SST for a compact, lightweight unit
- Modular design achieves redundancy and excellent expandability
Photovoltaic power generation PCS systems and storage cell battery systems
Used as disaster-readiness centers
Used as disaster-readiness centers
- Measures for business continuity plans
- CGS assistance
- Protection from instantaneous voltage sags
- Load leveling
High power density SiC inverters for HEVs
Highest power density class in the industry
Large-capacity, high-speed PM motors and inverters
Direct-drive equipment (faster, gearless)
- Magnetic-levitation bearings (low maintenance, eliminate need for lubricating oil)
- Output of 1,000 kW or more, 10,000 rpm or more
