    Will it work? Power supply Half Bridge

    An another question. The R3 in snubber is TOO HOT! Think, I must recalculate R3-C3 chain. I've got no idea how to do this. There are R3-100 Ohm and C3-2nF now in the circuit. Dq1-Dq2 - FR157 diodes.Q1,Q2 - are cold now.

    Will it work? Power supply Half Bridge

    Now working with TOP-switch part of power supply. Problem! Ive got only 2 type of cores. The most nearer gap is 0.1 mm more than calculated ( I have core with 0.7 mm gap, calculations says must be 0.59 mm). What should I do? how to resolve problem?

    Will it work? Power supply Half Bridge

    ir2110 power consumption Im going to use irf830 - low gate capacitance, about 600 pF. frequences 60-80 kHz this feedback - is not my idea, I could not proove that its not good :D 150 ns switch-on/off time IR2110 - it is not enough? Thanks a lot. Its my first SMPS 300 W project

    Will it work? Power supply Half Bridge

    half bridge gapped Please, make some comments about this design. Total power consumption about 300 Watts. Feedback - voltage from separate winding. R6 - Current sensor Connection LM3524 and IR2110 - I think must work properly. Thanks

    AVR register from C program

    Im working with avr300.asm file from Atmel (software master I2C). Simply make it accessible for IAR AVR C. Conversion between Atmel assembler to IAR assembler was succesful. The assembler program uses R16-R18 registers in my 2313 AVR chip to store variables. I need to write and read these...

    page which will check a subdirectory upon loading

    May be: you can use JavaScript to create file names like: ThumbName="thumb"+counter+".gif"; =thumb1.gif after this you must every time after loading picture check OnError event, If there will be an error you must stop creating ThumbName and stop creating HREFs. PHP is much more efficient but...

    parallel port programming

    chenycs Is there something associated with my question? :?: There is a lot of components giving access to hardware. I do dont need them. Hardware interrupt in EPP is a huge brake to slow down transmission... :!:

    parallel port programming

    Hi, does somebody use CreateFile with LPT descriptor on XP/2k platforms (file like access to LPT or COM ports). Is there any problems? comments? Want to transfer data from uC into PC in EPP mode. EPP transfer protokol will be emulated by uC fully. Thank for comments... :)

    IAR AVR C, Low/High byte of INT variable

    Need access to bytes of integer (16 bit). I can do this in case if I know the integer address: char *variable1 = (char*) 0xXXX; (address of integer) char *variable2 = (char*) 0xXXX+1; (address+1 of integer) is there any other way? char *variable1=(char*) IntVariable; -could not be compiled...
