Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/115226
Kind Code:
A1
Abstract:
Provided is a transformer-type power conversion device constructed so that the power consumption of a circuit connected to a primary side coil is balanced. A first transformer (TH) and a second transformer (TL) each have a secondary side coil (L2) having a positive output coil (LP) and a negative output coil (LN) which are different in output power. Which one of the two connection ends (P1, P3) of a primary side coil (L1) is connected to each of first and second power wires (W1, W2), which are two wires for connecting an AC power source (27) and the primary side coil (L1), is made to differ between the first transformer (TH) and the second transformer (TL). Alternatively, the polarities of the positive and negative output coils (LP, LN) are made to differ between the first transformer (TH) and the second transformer (TL).
