Provided is a power system for a hybrid vehicle, which relates to the field of hybrid vehicles. A first planetary gear mechanism (105) and a second planetary gear mechanism (104) that cooperate with each other are adopted, wherein a first sun gear (38) rotates with a first input shaft (11), a second sun gear (52) and the first input shaft (11) are independent from each other, the second sun gear (52) achieve different movement states through a first brake (26), a second brake (5)and a second clutch (8), to provide different transmission ratios, so that the power system is simple in structure, low in cost and more flexible in adaptability. Further, a second motor (102) is connected with the input shaft through the second planetary gear mechanism (104), can reduce the speed of the second motor through the planetary gear mechanism, and increase the torque, to effectively reduce the size of the second motor or improve the acceleration performance of the vehicle.
