Mo to r Co n t ro l Ap p lic at io n K it KITMOTORDC250W24VTOBO1 3-p ha se Mo to r Co n t r o l Po we r C ard 24V, 250W motor drive power card for XMC1000 and XMC4000 User Manual About this document Scope and purpose This document describes in technical details the implementation and use of a 3-phase motor drive power card. The card has been designed to operate in various configurations and coditions, such input voltages and control algorithms. The hardware is compatible with XMC DriveCards and DAVE configurations. Attention: This board is intended for evaluation purposes only and is not intended to be an end product. The design of this board originates from the need of a simple and plug-and-play motor drive power card to be used for XMC evaluation purposes in motor drive applications. The layout of the board has been studied to offer a good starting reference to designers. Intended audience Design engineers approaching a low-voltage motor drive system either in H-Bridge or in 3-Phase full bridge configuration. 1 Table of Contents 2 1 Introduction .................................................................................................................... 2 3 2 Block diagram ................................................................................................................. 3 4 3 Hardware description ....................................................................................................... 4 1 Revision 1. 0, 2019-03-20 KITMOTORDC250W24VTOBO1 User Manual Introduction 1 1 Introduction 2 This document describes the features and hardware details of the 3-phase motor control Power Card which 3 is designed to work with Infineons DriveCards. DriveCards are microcontroller boards with isolated debug 4 interface best suited for motor control applications. This power board works with DriveCards 5 KIT XMC1300 DC V1 and KIT XMC4400 DC V1. 6 7 The 3-phase motor control Power Card is designed to work under several supply voltage levels which are 8 described in TABLEXX. A first buck converter produces the regulated 12V supply for the MOSFETs gate 9 driving and a second buck converter generates the regulated 5V supply for the microcontroller and the 10 analog signal conditioning. 11 The 3-phase bridge is composed by three Half-Bridges with SO8 gate driver IC and SSO8 power MOSFETs. 12 Each leg provides a shunt resistor with amplifier for reconstruction of the phase current. A DC-link shunt is 13 also provided. With the provided shunts configuration, the board provides flexibility to adopt many different 14 control algorithms. 2 Revision 1. 0, 2019- 03- 20
