    Hi:

    I need to alter the polarity of a high voltage source connected to a load at around 1 hz.

    I have a high voltage (2.5 kv) power supply that has positive and negative outputs that can be floated to any ground reference. I basically need a high voltage H-bridge. Current is minimal, in the order of microamperes.Space is a very important aspect in the design.

    Do you have any ideas on how can this be achieved? (High voltage transistors, mosfets etc)

    Thanks

    Fernando

    single diodes:
    Vishay/General Semiconductor
    GP02-40-E3/54 4kv 250mA
    GP02-30-E3/54 3kv 250mA

    There is a way of using three 1kv diodes in series. (you will need to add 10Mega ohm resistors across each diode) (high voltage resistors)

    Bridge:
    IXYS
    UGB3132AD 4800V 1.3A
    UGD6123AG 7kv 1.8A
