Demonstration Board EPC9167 and EPC9167HC Quick Start Guide
●The EPC9167 demonstration board is a 3-phase BLDC motor drive inverter board featuring the EPC2065 eGaN FET 3.6 mΩ maximum RDS(on), 80 V maximum device voltage. The EPC9167 is provided in two configurations. The standard configuration (EPC9167) uses single FET’s for each switch position and the high current configuration (EPC9167HC) uses two paralleled FET’s per switch position and can deliver up to 42 Apk (30 ARMS) maximum output current. The board can also be configured for multi-phase DC–DC conversion and the EPC2065 supports PWM switching frequencies up to 250 kHz in motor drive applications and 500 kHz in DC-DC applications. The EPC9167 contains all the necessary critical functions circuits to support a complete motor drive inverter including gate drivers, regulated auxiliary power rails for housekeeping supplies, voltage, and temperature sense, accurate current sense, and protection functions. The various functional blocks are shown in figure 1. The EPC9167 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 EPC2065 eGaN FET with wide input DC voltage ranging from 14 V to 60 V
●Dimensions: L x W = 130 mm x 100 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 (option to choose between in- line and leg shunt current sensors)
●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 EPC9167
●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.
