New two-in-one 600 V PFC + inverter intelligent power modules (IPMs) for 3-phase motor drive simplify & speed implementation, time-to-market
Reinforcing the company’s position as a leading supplier of IPMs, the company’s new STK57FU394AG-E (15A) and STK5MFU3C1A-E (30A) are advanced 600 V IPMs that integrate a power factor correction (PFC) converter, three-phase inverter output stage, pre-drive circuitry and protection in a single, compact package. High levels of integration help to reduce part count and board space compared to discrete designs in applications that include motor control, inverter control and HVAC systems. Microcontroller-compatible low-voltage input and status outputs support further component and space reduction by eliminating the need for photocouplers between a host micro and the IPM.
The devices feature built-in cross conduction prevention, which reduces the possibility of system malfunctions caused by noise, and over-current protection for both the inverter and PFC section. Under-voltage lock-out ensures IGBT gate shutdown in the event of abnormal conditions. The devices are certified to UL1557 and offer an externally accessible embedded thermistor for high-precision monitoring of the temperature of the insulated metal substrate.
