As the local industry adapts to global trends and shifts from traditional AC design to BLDC motors, R & D engineers worldwide will face various problems. To help designers meet these challenges, Fairchild Semiconductor Corporation (NYSE: FCS) China ’s Global Power Resource Center (Global Power ResourceSM, GPRC) has developed a reference design for BLDC motor controller applications . The reference design uses SPM® intelligent power modules that include power factor correction (PFC), allowing designers to simplify designs, reduce bill of materials, and quickly develop prototypes.
The reference design RD-401, when used to design PMSM motor drive solutions up to 200 W, supports the inclusion of FCM8531 three-phase PMSM / BLDC controller, FSB50550A intelligent power module, FAN6961 boundary mode PFC controller and FSL306LRN green mode Fairchild压 开关。 Pressure switch.
The key features of this solution include:
· PMSM motor drive overall solution
· High power factor, low total harmonic distortion
· Wide Vin range: 90-265VAC
· PFC enable / disable optional
· Each functional module can be evaluated individually
· The demo program is pre-programmed
· Each circuit module has rich protection functions
The reference design RD-401 is available on the Fairchild Semiconductor website: http: //RD-401.pdf
RD-401 optimizes the PCB layout, current sampling circuit and current sampling algorithm, thereby successfully solving the difficulties encountered by designers when transitioning to BLDC design. The solution uses the FCM8531 controller and supports a variety of different reference designs and an integrated development environment-the Motor Control Development System (MCDS), which contains three drive modes. Developers and design engineers use these tools to quickly implement motor drive designs and immediately evaluate results.
In addition, the new reference design also includes a power factor correction (PFC) module to improve power transmission efficiency. In addition, the PFC module can also be used as a voltage pre-regulator. It can convert a wide input voltage range, 90-264 VAC to 400 VDC and lower. In this way, power devices and motors can use smaller current ratings while outputting higher power.
"This new reference design is fully functional and contains all the circuits needed to run the motor," said Wang Jian, Fairchild Semiconductor's China sales director and Asia Pacific motor control product director. "The customer only needs to connect three wires to the motor. In addition, the PFC function can be disabled by simply disconnecting the jumper, so that the customer can easily evaluate whether the PFC improves the performance. The debugging and development interface can be further adjusted. And optimization. The design is cost-effective and energy-saving, so it can provide customers with the best time to market. "
Fairchild ’s power components and motor control design support for home appliances and industrial applications can meet consumer and legal requirements for more energy-efficient and better performing home appliances and electronic equipment.
Fairchild's Global Power Resource Center (GPRC) is a valuable resource for system design engineers, allowing them to quickly achieve design differentiation and shorten time to market. The purpose of establishing a resource center is to provide innovative and efficient power management and mobility solutions for local and global applications. The solution was developed by the Global Power Resource Center in China. The company also has global power resource centers in Greater China (Shenzhen and Taipei), the United States, Germany, South Korea and Brazil.
