Fairchild Introduces New SPM™ Devices for Full-Switching PFC in 3-6kW Motor Drive Systems
Fairchild Semiconductor (NYSE: FCS) introduces three new Smart Power Modules (SPM®) designed for full-switching power factor correction (PFC) in motor drive applications in the 3-6kW power range. As highly integrated modules, PFC-SPM devices save 50% board space compared to discrete solutions, and increase reliability with built-in protection features.
PFC-SPM® products are ideal for reducing component count and board space while increasing system reliability and efficiency in air conditioners and industrial inverters
These devices also provide 99% power factor (typical) to meet the mandatory PFC standard (IEC61000-3-2) and 40kHz switching operation to mitigate power loss. Fairchild’s PFC-SPM devices offer a solution ideal for air conditioners and industrial inverter designs by increasing system reliability and efficiency while reducing board space.
These PFC-SPM devices enhance reliability in end systems by integrating a thermistor for temperature monitoring and a shunt resistor for current sensing. The built-in resistor also reduces part count by eliminating the need for the external bulky components required by discrete solutions. Further reliability features include under-voltage (UV) and over-current (OC) protection provided by their integrated gate-driving IC. They also provide an isolation voltage rating of 2500Vrms/min and their packaging complies with basic creepage and clearance spacing for UL certification No. E209204.
