so Power=-11e3*0.98*0.99 for inverter, Power=11e3*0.98*0.99 for PFC? right?

Forum Post: RE: TIDA-010933: Some queries to use the reference design
Hi Alpesh, 1) Yes, you can follow the schematic for your design. 2) If you are not going to use battery, than you don't need SoftStart schematic on the left side (with MOSFET) but the MPPT stage on LMG2100 will remain the same. The VIN pin is not only "Voltage In". I use this device as Boost converter when operating from PV panel, so the current going into SW pi and comun out from VIN pin. In CLLLC stage, two LMG2100 create a full bridge. In full bridge one leg is sourcing current and another is sinking the current. 3) This is one of the features of the design - the lead inductor is build in the transformer. No need of external inductor. 4) For testing purposes we have 5V jack connector on the board. But in real application there is LM5164 buck converter for self power supply. This converter is powered from 75V rail. At the startup a PV panel will charge 75V bus to some voltage through LMG2100 body diode. Then the board will be powered up and start operation. 5) The MPPT stage operates as current source for the 75V rail, so MPPT stage is pushing current to the output to maintain MPPT. The 75 rail is not directly reguated. The 75V rail and the 400V DC Link are coupled with fixed frequency CLLLC. The DC/AC stage is regulating 400V DC Link voltage and as consequence indirectly regulates 75V bus too. Please let me know if something is still unclear. Best regards, Seva.

Hi Utku, CHG_wake: This is a wake signal connected to BQ76952 TS2 pin to wake AFE after charger attached. If you don't need charger detection, you can remove this circuit but you also need a wake up signal connected to TS2 pin. This signal can come from MCU or switch ... Charger reverse and Pack_adc ports: These two ports have same purpose: detect PACK- voltage. Different is pack- voltage at charger reverse is higher than short circuit. So we design two resistor divider to monitor different pack- voltage at different senerios. Pack_en: this is a control signal from MCU, you can enable Pack_en to monitor PACK- voltage. LD_wake: when load attached, LD_wake turns high to wake MCU(start ADC conversion etc.) BRs Kian

Hi Tom, Yes you can. You should notice the current flow from BAT+ to UPGND which may cause IR drop affect measurement accuracy. But if you only have AFE on high side. it is okay to connect them together. BRs Kian

I want to connect my pack to TIDA-010247. VC0 ~ VC10 connect to bottom BQ76942 and VC10B ~ VC20 connect to top BQ76942. Is it okay to connect VC10B and UPGND together?

Forum Post: RE: UCC3895: Using the UCC3895 below 50kHz
Based on the oscillator block below, if Rt is too small, the current mirror may not be linear anymore. Other than that, I don't see why you cannot set the freq lower. Please refer to this threads as well. https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/811239/ucc2895-ucc2895---minimum-frequency https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/699388/ucc2895-ucc2895 I think you can set it to lower frequency and the best way is to try it on your board.

Forum Post: RE: TPSM53603: TPSM53603:
Hello, Thank you for your question. The minimum input voltage for proper PGOOD function in this part is 2 V. Once the output voltage rises above 94% of the set output voltage, the PGOOD pin will rise to the pullup voltage level. The PGOOD pin will be pulled low when the output voltage drops lower than 92% or rises higher than 107% of the set output voltage. Please see section 7.3.7 of the datasheet for more details. Thank you, Joshua Austria

Part Number: TIDA-010933 Tool/software: Hi Experts, Good day! May I kindly ask if you could provide a detailed description of the implementation of TIDA-010933 embedded software? I found the implementation in "TI Resource Explorer": https://dev.ti.com/tirex/explore/node?node=A__AChTCMdmd93MwyOxrNnbsg__digital_power_c2000ware_sdk_software_package__5C6SEVO__LATEST For example in uinv_main.c line 293-379. What mathematical or control theory applied to those codes? I'm not an expert on the SMPS design and we would like this design used for supporting around 24-28VDC input. Thank you so much in advance for your support. Regards, Jonathan
