    Hi friends,

    We are working on a project for developing a HIGH VOLTAGE POWER SUPPLY,
    Around 15 Kv for co2 Laser.

    At present we have power supply using 1N4007 with Vrrm (Peak
    inverse voltage of 1000 V).We are using 80 Diodes in series in a diode bank,
    To get an output of 15Kv.

    Now we want to use diode of Piv or Vrrm= 15Kv (Diode no. HV05-15).

    So please tell me what are the values of Ceramic capacitors and Resistances.

    Also tell us the formulas for these calculations.

    DATASHEET OF DIODE
    Part name= HV05-15

    Vrrm or PIV 15 kv

    Vrms 10.5 Kv

    Vdc 15 Kv

    If(av) 550 mA

    Repetitive Peak Reverse Surge Current...IRSM 100 mA

    Non-Repetitive Peak Forward Surge Current...IFSM 200 A

    Units



    Peak Repetitive Reverse Voltage -VRRM

    RMS Reverse Voltage -VR(rms)

    DC Blocking Voltage -VDC

    Average Forward Rectified Current -IF(av)

    Peak Forward Surge Current(Non Rep) -IFSM

    Peak Reverse Surge Current -IRSM

    Operating & Storage Temperature Range

    Maximum Forward Voltage -VF

    Maximum DC Reverse Current -IR
