Isolation Device Solution For Intelligent Power Module (IPM) Drive To Realize High-Accuracy Industrial Equipment In High Noise Environment

Reducing the dead time of an inverter, while driving high-speed power devices that reduce switching loss.


As efforts to protect the environment have advanced, the use of inverters in industrial applications and green energy systems have continued to grow rapidly as a way to achieve low-power motor control and reduce power conversion loss. In recent years, this demand has been increasing more and more in relation to Sustainable Development Goals (SDGs). Further improvement in accuracy and downsizing of equipment are required. This white paper focuses on the new Renesas Photocoupler RV1S9x61A and RV1S9x62A for IPM drive which resolve these market demands. These products make it possible to reduce the dead time of the inverter, and are isolation devices with optimum characteristics for driving high-speed power devices which reduce switching loss.
