Hi Tostino!

I apologize for not being helpful. I have pretty much soldered all the MOSFETs onto the circuit boards prior I saw your post here. Let me see what I can do with the next badge of orders and get back to you.

Hi Knuckles!

I valued your informative suggestions. You are truly the godfather of all Infineon controllers. I really appreciate it. :)

Best Regards,
Edward Lyen

The VR circuit components are susceptible to burn out from initial current surge.
These components only have a max rating of 100V to 120V. The resistors are maybe 1/8 watt.

I use a FJP9100 transistor circuit to keep the voltage to the VR circuit under 100V.
Side benefit of this mod is it makes the unit "any voltage" 39V to 150V.

I also add a temp switch to the fet heat sink.
Very simple to solve all these issues with a mod "module".

PM me and I'll share all my mods with you.
This way your controllers will be "bullet proof"

Confirmed > no overheating issue on SMD resistors

Post by Lyen » Jun 04 2010 4:16am

Dear all respective members and buyers,

Good news!

This is the clarification and response to the potential overheating issue on the SMD thin film resistors on R10, R11, and R12. I have escalated it all the way to the supplier as well as actual designers for the print circuit board. We both have executed a series of testing including highest voltage, highest temperature, highest motor rotation, as well as highest current drawn. The resistors on R10, R11, R12 pads actually do not take direct voltage from the battery. Therefore, the current and power draw is more than sufficient with the SMD resistors.

Here is the hard evidence with the tested results executed in San Francisco, California, USA:

The voltmeter and the EC-124115-LYEN Edition controller being used for testing at 155.9V (Do not try this at home! It is very dangerous!) :shock:
Image

Temperature meter with the probe sensor being used (The probe is quite sensitive) :)
Image

R10 resistor temperature result shown in Celsius after one full hour:
Image

R11 resistor temperature result shown in Celsius at the second full hour:
Image

R12 resistor temperature result shown in Celsius at the third full hour:
Image

As you can see, the overheating issue was incorrectly informed previously. We can conclude the case is now dismissed. :D

Your Truly,
Edward Lyen

#1) Buy from Lyen. I like Lyen and I think he builds EXCELLENT controllers. A+ Lyen.

#2) This statement is incorrect ...
Lyen wrote:The resistors on R10, R11, R12 pads actually do not take direct voltage from the battery.
This is false. R10, R11, R12 resistors absolutely DO take direct voltage from the battery.

#3) I just measured the current thru the R10-R11-R12 circuit on an isolated "naked" XieChang pcb.
At 152 volts the current thru this circuit is 8.6 ma just as I had predicted.

#4) Fortunately the 12-fet controller tested by Lyen has a large capacitor directly above R10 and R11.
Clearly this large cap is acting like a heat sink and helps "save" these components from overheating.

Please realize that the 6-fet, 18-fet, 24-fet and 36-fet MAY NOT have a large cap directly above the R10 and R11 'lil' resistors.
Just a FYI to all the folks whom like math.

Buy Lyen ... Stay lean!

cheers,
-Knuckles

Hi Knuckle!

I thanks again for your commentary and compliment. The direct battery connection was actually interpreted incorrectly as the original word by word translation meant connect both positive & negative to each individual component such as the resistor from end to end. :)

Anyway, I am seriously listening and made the change to make sure the controller is 100% reliable and last for years although it is not really necessary. The higher wattage resistors are now used. Below is the improvement:

Hey Everyone,

For all of you that know me i have run a 24 mosfet irfb 4110 controller with 145v of a123 for months .. even before lynn has released his controllers in for sale thread

Lynn

You must modify r115 as per knuckles .. IT WILL FAIL; I gaurentee it, I've had failure 2 times since march 2010; that ive been running this controller

R10, r11, r12... WILL BURN OUT

the current is to high ..

I could even take a photo of the resistors on my board... the resistors are turning brown due to the heat over last 3 mnths

I don't want to hurt your thread... but buyers must beware that if they but this board .. it will faill .. may not be for a few months ... but it will happen..

Hello Steveo!

Thanks for letting me know another potential failure. Yes, please take a picture of your "browned" resistors on your circuit board. May I also ask what was circuit board revision that failed on you? I appreciate it!

Thanks.

Hi, Lyen,

I have a few questions on the controller I just received from you:

:arrow: You posted the mod June 5, and sent mine out June 9. Does it have the resistor mods to it as pictured above? I just want to make sure.

:arrow: . Your screenshot on page 1 shows parameters for an 18fet (EB218) board. All the examples I find from Methods are for EB218 boards as well. Can you provide the .asv file for this EB212 (12 fet) board showing the default values for all the parameters ?

:arrow: Can you just change and flash one parameter value, or do you have to populate them all ? I don't want to upset the rest of defaults values.

Thanks in advance for your help. :mrgreen:

Here is the remedy. I have engaged a bunch of people from the manufacturer for the potential issues that was mentioned by the young fellow Steveo again. I was told by the engineer and designer of the circuit board being used was good as is. But to relief the worrying of people, here are more changes as shown on the pictures below. The R115 resistor will not turn brown. The possible reason was because Steveo operated his controller at 145-150v which was not safe to begin with. The engineer told me the R115 resistor can sustain 15 degree Celsius above normal operation temperature. The engineer has also said switching power circuitry for voltage regulation is embedded onto the circuit board, so the additional VR or voltage regulation circuitry is unnecessary. Resolved. :)

Hi Lyen, in a PM you mentioned 18 Fet and 12 Fet.

I have a basic notion, more fet's = better.

Is this correct.

How much is the 18 Fet controller?

Thanks.

Hi Mighty!

Here is the link for the 18 FET High Voltage controller I am also selling:
http://endless-sphere.com/forums/viewto ... 31&t=18605

In theory, more MOSFETs can generate more power with less heat. But a properly optimized configuration between battery and motor and price are also important. In addition, enclosure size, range, weight, and battery discharge ability should be consider. :)
