Circuits

• Secondary windings (a) or transformer output (b) can be connected in series to increase output voltage
• The important factor is the winding sense or phase, indicated by the red dot
• If cascading transformers (c) it is important not to exceed the winding to core insulation voltage limit
• Connecting transformers in parallel is deprecated as unless the windings are absolutely identical there will be circulating currents between them
