Renesas Electronics Introduces New 100 kW Inverter Solution

Renesas Electronics Corporation (TSE:6723), a leading global semiconductor solutions provider, today announced a new 100 kW inverter solution that delivers an industry-leading 3.9-liter (L) small design grade for use in SUVs including SUVs 100 kW class high power motors for medium to large hybrid vehicles (HEVs) and small and medium sized electric vehicles (EVs).

Renesas Electronics will offer new solutions in the form of solution kits, including software for improving HEV/EV motor performance, microcontrollers (MCUs), insulated gate bipolar transistors (IGBTs) and fast recovery diodes (FRD) And other hardware components, as well as other power semiconductor devices.

The new solution helps system developers reduce the time spent on development steps: from specification analysis to hardware and software development and motor characterization. For example, inverter prototype development time can be reduced from two to three years to one year, and the cycle is shortened by more than 50%, thereby greatly reducing development cycle and cost.

Carbon dioxide emissions are rising due to abnormal weather events and increased levels of environmental pollution caused by global warming. For the automotive industry, the need to reduce carbon dioxide emissions and the large-scale adoption of electric systems (such as HEVs and EVs) as soon as possible will be further enhanced.

In an electric system, the main function of the inverter is to convert direct current (DC) electricity into alternating current, and control the motor to adjust the speed and current according to changes in driving conditions. Therefore, in order to improve the fuel and power efficiency of the inverter system, in addition to the need to miniaturize the inverter, a high-precision and high-efficiency motor drive system is required to mount the electric motor in a limited space of various types of engine rooms. Device. Renesas Electronics' latest miniaturized inverter solutions address these needs.

Renesas Electronics has been developing a portfolio of inverter solutions for a long time. In 2014, Renesas developed a solution that achieved a size of 2.9L at a rated 50 kW level. To meet the growing demand for large-output motors for large vehicles, Renesas Electronics has introduced a new 100 kW inverter solution with motor calibration tools to expand its product lineup to support these high-power motors.
