  • TIDM-1000: Testing

    Part Number: TIDM-1000 Hi Team, Could you do a test regarding a 200-ohm load? When the input voltage is 120V, the load is 200 ohms, and the bus voltage is 400V. I'd like to see if it can be stabilized at 400V without current fluctuations. Kind regards…

  • TIDM-1000: VIENNA

    Part Number: TIDM-1000 Hi Team, Does DC-link voltage must be larger than 2*√2*AC RMS voltage? My customer found this on https://unitedsic.com/fet-jet/ Vienna's part. He want to know if this reference design needs to respect this rule. -- Thanks…

  • TIDM-1000: TIDM kit control algorithm

    Part Number: TIDM-1000 Hi Team, There is an issue from the customer need your help: For current ring and voltage ring control of the kit, only known from the user manual is current ring P control, voltage ring PI control. What about the set of control…

  • TIDM-1000: A debugging issue

    Part Number: TIDM-1000 Hi Team, 1.负载200欧的时候，输入相电压120V，输出直流电压400V，建立BUILD2电流环，ilref=0.2,时，测的相电流波形如图所示，无法达到参考电压400V，请问电流波动的原因？ 2.测试过程中出现过流保护，，是什么原因造成的。 1. When the load is 200 ohms, the input phase voltage is 120V, and the output DC voltage is 400V. When…

  • TIEVM-VIENNARECT: TIDM-1000

    Part Number: TIEVM-VIENNARECT Other Parts Discussed in Thread: TIDM-1000 Hi Team, Here're two issues from the customer need your help: 1. In the program given by TI, is the meaning of each variable provided? 2. Can the resistance value of the third…

  • TIDM-1000: Gate Drive overheating

    Part Number: TIDM-1000 Other Parts Discussed in Thread: UCC21520 Hi, I have scaled up the reference Vienna design to run from a higher supply voltage, using Microchip/Microsemi Silicon Carbide mosfets as my switching devices. This has been mostly successful…

  • TIDM-1000: boardstatus_BuslmbalanceTrip

    Part Number: TIDM-1000 Hi team, Here's an issue from the customer may need your help: When the kit is loaded at 300 ohms, the input phase voltage is 70 V, and Bulid2 is established, and active rectification is not started. Monitoring the output with…

  • TIDM-01000: TDIM-1000 Control

    Part Number: TIDM-01000 Other Parts Discussed in Thread: TIDM-1000 Regarding the TIDM-1000.. Is this design using Park and Inverse Park transforms to do the control of inner and outer control loops? Is Clarke transform involved? Can the Power Factor be…
