750W馬達控制板KIT_XMC750WATT_AK_V1
The motor control application kit KIT_XMC750WATT_AK_V1 is designed for use with 230V AC mains power supply. The drive cards provide a galvanically isolated debug interface that allows safe software development.
A PFC circuitry can be controlled by the on-board PFC IC or by the microcontroller at the drive card. The power inverter bridge is built by 6 discrete IGBTs in DPAK package. Each leg provides a shunt resistor with amplifier for phase current measurement. The DC-link also provides a shunt resistor with amplifier for reconstruction of the phase current with single shunt method. An additional low pass filter allows measuring the average DC-link current as well. The power supply for the control devices as well as the drive card is provided by a non isolatedflyback converter which provides 5V and 15V DC. The auxiliary power board connector allows adding an inverter card in order to use the board together with the XMC4400 drive card as dual inverter.
The main use case for this board is to demonstrate the generic features of the XMC microcontroller devices including tool chain. The focus is the operation under evaluation conditions. The board is neither cost nor size optimized and does not serve as a reference design.
