The AC power for the Gold Bassoon can be delivered from either directly from the mains or from a
single or three-phase isolated transformer. The following sections contain topology
recommendations for implementing three-phase and a single-phase supply chains.
The power stage of the Gold Bassoon is fully isolated from the other sections of the Gold Bassoon,
such as the control-stage and the heat sink. This isolation allows the user to connect the common
of the control section to the PE, a connection which significantly contributes to proper
functionality, safety and EMI immunity, leading to better performance of the Gold Bassoon.
This isolation allows the Gold Bassoon to operate with a non-isolated source (a direct-to-mains
connection) which eliminates the need for a bulky and expensive isolation transformer.
As well as operating from a non-isolated/direct-to-mains AC supply, the Gold Bassoon can also
operate from an isolated transformer.
The AC voltage level must be limited to 270 VAC so as not to exceed the maximum supply voltage
drive.
