We Claim:
1. An integrated powertrain for a vehicle comprising:
an on-board charger (OBC) (103); and
an auxiliary power module (APM) (107); wherein the OBC (103) and the
5 APM (107) share an integrated inverter circuit (111).
2. The integrated powertrain as claimed in claim 1, wherein the integrated inverter circuit
(111) is connected between a power factor correction (PFC) rectifier (101) and a first
transformer (103b), a second transformer (107b).
3. The integrated powertrain as claimed in claim 1, wherein the integrated inverter circuit
10 (111) is configured to participate in independent charging of a traction battery (105) and
an auxiliary battery (109) along with supplying power to auxiliary loads.
4. The integrated powertrain as claimed in claim 1, wherein the integrated inverter circuit
(111) in charging state is configured to charge an auxiliary battery (109) from a utility grid
using a second transformer (107b).
15 5. The integrated powertrain as claimed in claim 1, wherein the integrated inverter circuit
(111) in running state is configured to charge an auxiliary battery (109) from a traction
battery (105) using a first transformer (103b) and a second transformer (107b).
6. The integrated powertrain as claimed in claim 1, wherein the integrated inverter circuit
(111) in a first integrated inverter circuit configuration (111a) includes at least three legs
20 (a leg (L1), a leg (L2) and a leg (L3)), wherein each leg includes at least two circuit
elements.
7. The integrated powertrain as claimed in claim 6, wherein the at least two circuit
elements in each leg include a switching element or a non-switching element or
combination thereof.
25 8. The integrated powertrain as claimed in claim 7, wherein the non-switching elements
are configured to generate a current in a first transformer (103b) of the OBC (103) and a
20
second transformer (107b) of the APM (107) to have sinusoidal nature, such that their
power loss reduces
