Main Inverter (Traction Inverter)
The main inverter plays a critical role by converting DC power stored in the battery into AC power to drive the motor.
ROHM supports this function with a comprehensive range of components, from Si MOSFETs, isolated gate driver ICs, and control ICs to power management ICs and shunt resistors, contributing to the miniaturization of inverter units while helping extend the driving range of electric motorcycles by improving overall system efficiency and performance.
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.
Topology Selection
When designing power supply circuits, it is necessary to select a circuit configuration (topology) that meets the required specifications, as the input/output voltages, power, isolation, and other factors will vary depending on the application. Selection of the optimal components will also differ based on the topology. Selecting the wrong components can lead to a failure to meet the required specifications, necessitating a complete redesign of the circuit. ROHM’s topology selection page guides users in selecting the optimal devices for various topologies.
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.
