描述

AC Drive is a variable-speed controller that precisely controls the shaft rotation speed, typically, an induction motor or synchronous motor. They are widely used in industrial machinery such as production line conveyors, cranes, elevators, fans, pumps, and compressors. As the need to save energy grows worldwide, there is widespread demand for an inverter control to boost energy efficiency. The performance and multifunctionality of inverters continue to improve. This is due to advances in simple controller functions, interfaces such as field networks of various types and USB, and display panels enhancing usability. At the same time, there is growing demand in emerging economies for inverters that are cheaper and more compact.

In response to these varied requirements, Renesas offers a broad lineup of products that provide scalability. The RX Family of 32-bit microcontrollers (MCUs) provides an array of on-chip peripheral functions such as multifunction timers and A/D converters optimized for inverter control, Ethernet and USB interfaces, and serial interfaces. Also available with analog and power devices suitable for inverter applications.
