Motor Drive: 3-Phase 400VAC Inverter
Inverters must operate efficiently and deliver high power to drive large current motors with minimal energy loss.
ROHM supports these requirements with motor drive power solutions that incorporate state-of-the-art power semiconductors centered on SiC MOSFETs, high performance magnetically isolated gate driver ICs, and high-precision shunt resistors. ROHM also offers a broad lineup of power supply ICs for auxiliary power supplies, enabling system-level solutions that contribute to high efficiency operation with improved reliability.
Topology Selection
When designing circuits, especially power circuits, it's essential to choose a circuit configuration that aligns with the required specifications, as the input/output voltages, power levels, and isolation needs will vary by application. Optimal component selection also depends on the topology. Using inappropriate components can lead to performance shortfalls, potentially requiring a complete redesign of the circuit. ROHM’s topology selection page helps users identify the most suitable devices for various circuit designs.
Reference Design
ROHM provides a system-level evaluation board (solution board) that combines ROHM's IC and discrete products. We have already solved not only the characteristics of individual products but also the problems that may occur when combining them to build a system, thus contributing significantly to the reduction of development time for our customers.
Design Model
ROHM offers simulation models, including thermal models, PLECS models, and Ray files, for circuit and thermal simulations of discretes and ICs, including power devices.
ROHM Solution Simulator
ROHM Solution Simulator is a new web-based electronic circuit simulation tool that can carry out a variety of simulations, from initial development that involves component selection and individual device verification to the system-level verification stage.
