Power

Hello,

We are developing a 3.3kW On Board Charger for Automotive domain. Our full requirement is as follows:

1. Application: Automotive grade ON Board Charger
2. Power: 3.3kW
3. Vin_ac = 90-270VAC
4. Input Frequency = 47-63 Hz
5. Vout_dc = 40-60VDC
6. Nominal Vout_dc = 50.4VDC
7. Max output current = 63A
8. System Efficiency = >95% @ 180-270VAC, full load and >96% @ 230VAC, full load

We are looking at following DC-DC solutions:

1. https://www.infineon.com/cms/en/product/evaluation-boards/eval_3k3w_llc_hb_cfd7/
2. https://www.infineon.com/cms/en/product/evaluation-boards/eval_3k3w_bidi_psfb/

First eval board is using half bridge LLC and the second one is using phase shift full bridge for the same rating of 3.3kW power. I have following queries:

1. Which one is best suited topology for our requirement?
2. Does constant current and constant voltage modes are supported by the charger’s control loop?
3. How controller adjusts the charger control loop? Will you provide the source code for the same?
4. Please provide the design consideration documents to change the rating of the components.

Looking forward for your expert support.

Thanks and Regards,

Vikas Dwivedi

兄弟们，我想利用数学模型计算SIC MOSFET的损耗，自己推导公式如下，计算结果与datasheet的Eon结果偏差太大，看论文中考虑了寄生电容的非线性，采用了了分阶段恒定电容模型，猜测是这个导致的偏差，我用的管子FF6MR12W2M1P_B11

hi，we have encountered the click noise issue when press power off key to power off the unit in standby mode (no audio played this time), the irs2092 circuit is same as application note description. from the application note we know this chip have the click noise elimination function when power off, please advice why still occur the pop noise from speaker output of Tweeter, thanks.

Hi,

I have designed a custom board wherein there are two Infineon IRPS5401  and two IR38063 IC over a common PMBUS.

Two infineon IRPS5401 ICs are getting detected properly, but one of the IR38063 IC is not getting detected at all  and other one says unknown device( Refer attached .png file)

I am using latest version of PowIRCentre GUI with USB005 dongle and an external 12V supply  is being used to power on  the board. The address offset for the IR38063 ICs are 1B and IC respectively.

Followings are the intermediate findings:

1. For both the IR38063ICs, I am correctly getting  outputs on VCC pin (5.18V ) and P1V8  as 1.8V. 

2. The waveform for SCL and SDA looks clean.

Kindly suggest, what could be the possible reasons for this behavior? and what are the further debugging steps?

Hello

I'm using script into IMC102T.

I use a global variable which is read via serial communication.

This variable is refreshed in Task1 via many line into the script code.

So I place it under EnableCoherentUpdate /DoCoherentUpdate section.

This seems work when the the Task1 Number of instruction is < #SET SCRIPT_TASK1_EXECUTION_STEP .

Since I configure #SET SCRIPT_TASK1_EXECUTION_STEP  < Task1 Number of instruction, this coherent update seems not work because some time, some bits are not yet refreshed and pass to 0 value without any reason.

I try the following code where I force bit 0x2000 to be set... but sometime, I read this bit to 0...

It seems the coherent update is also flush RAM to Variable on each slice of execution of task1 ???

Modbus_Status is a global variable..

Task 1 Number of instruction: 103

#SET SCRIPT_TASK1_EXECUTION_PERIOD (40)
/*Defines number of lines to be executed every 10ms in Task1*/
#SET SCRIPT_TASK1_EXECUTION_STEP (10)

Task1:

 [.... Some code here ....]

EnableCoherentUpdate();

/* Motor Speed Status */
if ( SwFaults == 0)
{
Modbus_Status = (abs_MotorSpeed / 60);
}
else
{
Modbus_Status = 0x8000; /* Motor fault Bit 15 */
}
/* ----- Bit 9 : Start/Stop -------*/
if (FSM_State == FSM_ON)
{
Modbus_Status = Modbus_Status | 0x0200;
}
/* ------ Bit 10 : Direction -------*/
Modbus_Status = Modbus_Status | CurrentDirection;

/* ------ Bit 11 : RBrake over load capacity -------*/
if (VDCBus_RBrakeState == VDCBUS_RBRAKE_STATE_FAULT)
{
Modbus_Status = Modbus_Status | 0x0800;
}

/* ------ Bit 12 : Temp Motor error -------*/
if (GPIO7_IN == MOTOR_TEMPERATURE_NOK)
{
Modbus_Status = Modbus_Status | 0x1000;
}

/* ------ Bit 13 : E9 24V (input Enable) -------*/
// commented for test  if (GPIO15_IN == E24V_OK)
//{
Modbus_Status = Modbus_Status | 0x2000;
//}
/* ------ Bit 14 : PFC error -------*/
if (PFC_SwFaults > 0)
{
Modbus_Status = Modbus_Status | 0x4000;
}

DoCoherentUpdate();

Hello

Regarding IDP2303A, I have 2 questions : 

1. Are the configurable parameters (datasheet, section 3.8.2 Configurable Parameters ) one time programmable ?

2. If they are one time programmable, I need more  information regarding how to correctly adjust from the first time the  startup parameters of the LLC stage , considering that right now my power supply starts only at 66% of full load . 

Dear Infineon Support,

I am currently designing with the BTF3035EJ chip and have purchased the Demoboard BTF3xxxEJ (PN: BTF3035EJDEMOBOARDTOBO1) to validate the chip for my function. The Firmware engineer I'm working with and I would be very interested in the zip package mentioned in the datasheet that supposedly contains Demoboard_Aiko_Universal.ino Arduino example code. I had submitted a support request previously to no response. I was able to find the GUI of the same name in a separate product's downloads page, but not the Arduino Sketch.

It was not sent with my purchase confirmation (and perhaps that's my mistake for ordering through mouser), nor is it anywhere in your downloads or available anywhere on the vast internet.

Can I be provided with the .zip file that is supposed to come with the Demoboard BTF3xxxEJ/BTF3035EJDEMOBOARDTOBO1

Thanks,

Hello,

I'm using the IMC102T.

I configured to detect the AC under Voltage (180V)

According the user manual, §2.2.2.3, it is say that in case of under or over votlage, the PFC goes to Fault State.

THis is the case.

But when voltage return back over 180V, the fault is acknowledged and the PFC state leaves FAULT to STOP.. Anf the PFC_FaultFlag return to 0!

The UM indicate we must make PFC_FaultClear.

I think the need of clear ourself the fault is a correct behavior.

CUrrently, if a brief under voltage occurs, the PFC goes to fault, then to stop without any means to know what append!

PLease could you check that?
