Patent ID: 8333166

Claim:
A plasma treatment system comprising: a vacuum chamber; a power buss; a ground buss; a positive phase secondary electrode buss; a negative phase secondary electrode buss; a positive phase primary electrode buss; a negative phase primary electrode buss; a plurality of isolation transformers, each of said isolation transformers including a primary winding and a secondary winding, said primary winding having a first end coupled to said power buss and a second end coupled to said ground buss, said first ends of said primary windings coupled to said power buss in parallel, said second ends of said primary windings coupled to said ground buss in parallel, and said secondary winding having a first end coupled to said positive phase secondary electrode buss and a second end coupled to said negative phase secondary electrode buss; a first plurality of capacitors coupling said positive phase secondary electrode buss to said positive phase primary electrode buss; a second plurality of capacitors coupling said negative phase secondary electrode buss to said negative phase primary electrode buss; and a plurality of electrodes in said vacuum chamber, each of said electrodes coupled with said positive phase primary electrode buss or with said negative phase primary electrode buss.
