Title:
SECONDARY ELECTRICAL POWER SOURCE BASED ON MOTOVILOV TRANSFORMERS
Document Type and Number:
WIPO Patent Application WO/1994/021028
Kind Code:
A1
Abstract:
The known power source comprises input (G1,T) and output (G2,T) converter components with LT and MT converter cells, and T O galvanic cross coupling conversion transformers with bifilar windings (2, 9, 12, 16, 20, 22, 24, 26, 29); LO 2 and MO 2 converter cells are based on "Motovilov's transformers" and direct current power transformers each containing two symmetrical groups of windings and rectifiers, including some to effect pulse control of the direct current in the direct current power transformers. In order to reduce the effect of pulse and alternating current in the windings of the direct current power transformers and cross coupling conversion transformers on the leakage inductance Ls in the windings, and thereby also improve the source frequency characteristics, the function of cross coupling and voltage conversion in the source are split between the cross coupling conversion transformers (with a transfer factor of 1 and correspondingly lower Ls levels) and the direct current power transformers introduced for that purpose at G1,1 and G2,1 and intended for use with direct current (2, 9, 22, 24, 29); LO and MO converter cells with direct current power transformers for work with direct current are connected in a special multi-cell circuit characterized by voltage levels Y = 1+2L0(M0) at the circuit, the total power of all the converter cells being P < 2P1 where P1 is the power of the first converter cell; the purpose of the said circuit is to ensure smooth adjustment of the source output voltage without pulse current at the source output or in the direct current power transformers. It is further proposed that there should be a connection L1 2 and M1 2 of the converter cells in the multi-cell circuit shown (12, 16).
