Interference suppression
TopCon power supplies have integrated interference suppression. For
the interference protection components to be able to perform their func-
tion, the following conditions must apply:
Large area earthing suitable for EMI.
Shield mains and load connection.
Depending on load and installation situation.
Connect both ends of shields to earth.
Depending on load and installation situation.

Block diagram
The mains voltage is rectified and smoothed in a DC intermediate circuit
with capacitors. From this smoothed voltage a high frequency AC volt-
age is generated using a full IGBT bridge in the power section (printed
circuit board LP PWR); this features makes it possible to control the
output voltage using phase modulation.
