SK-POWER-3P-LV-MC

The SK-POWER-3P-LV is an evaluation board for low voltage motor control applications, mainly using BLDC (brushless DC) or PMSM (permanent magnet synchronous) motors. The board allows the designer immediately to start with the software development and evaluation of low voltage three-phase motor control applications before his own final target system is available. It is directly connectable to the Fujitsu SK-91470-144PMC1-MC Starterkit using the included 34-pin ribbon cable.

It is an extension board for these starter kits and serves as power stage (inverter) for brushless motor control applications using Fujitsu’s motor control MCUs.

The SK-POWER-3P-LV board includes the following features:

• Low-voltage power stage with gate drivers for three-phase motors
• Directly connectable to MB91470 and MB91480 Series Starterkits with –MC suffix (e.g. SK-91470-144PMC1-MC, SK-91F479-144PMC1-MC)
• Flexible power supply voltage system:
• DC link input (35V 10A max.) for motor current supply
• Logic supply from DC link or separate input 9-15V
• 10-20V gate driver supply (with optional 15V regulator) and 5V internal logic and analog supply, Power-LED
• Integrated current measurement for two phases and DC link current
• Integrated voltage measurement for all three phase voltages and DC link voltage
• Hardware over-current and over-voltage detection with LED, interfaced to DTTI input of Starterkit
• 34-Pin connector holds all relevant PWM and analog signals
• Chopper transistor + connector for external brake resistor
• RoHS compliant
