EPC9176 Demonstration Board Quick Start Guide; 20 ARMS, 3-phase BLDC Motor Drive Inverter using the EPC23102 ePower™ Stage IC
■The EPC9176 demonstration board is a 3-phase BLDC motor drive inverter board featuring the EPC23102 ePower Stage IC 6.6 mΩ maximum RDS(on), 100 V maximum device voltage. The EPC9176 can deliver up to 28 Apk (20 ARMS) steady state output current. The board can also be configured for multi-phase DC–DC conversion and the EPC23102 supports PWM switching frequencies up to 250 kHz in motor drive applications and 500 kHz in DC-DC applications. The EPC9176 contains all the necessary critical functions circuits to support a complete motor drive inverter including gate drivers, regulated auxiliary power rails for house keeping supplies, voltage, and temperature sense, accurate current sense, and protection functions.The various functional blocks are shown in figure 1. The EPC9176 mates with an assortment of compatible controllers, supported by various manufacturers leveraging existing resources for quick development purposes, that can quickly be configured as a motor drive inverter or DC–DC converter.
●MAIN FEATURES
■3-phase inverter based on EPC23102 eGaN IC with wide input DC voltage ranging from 14 V to 65 V
■Dimensions: L x W = 81 x 75 mm (including connector)
■Low distortion switching that keeps motor audio emission low and reduces torque ripple
■dv/dt optimized for motor drives less than 10 V/ns with option to increase dv/dt for DC–DC applications
■All current sense with high accuracy and bandwidth
■All phases voltage sense
■Voltage sense for the DC supply to the drive
■Housekeeping power for the various circuits and external controller derived from the main power supply to the EPC9176
■Temperature monitoring circuit
■Protection features including: over-current and input supply under voltage lockout
■Shaft encoder/Hall sensors interface connector for motor drive application with two voltage levels selection option
■The board can also be configured to operate as a synchronous buck DC–DC converter.
