“…(2)). For this purpose, assuming that the parameters of both the converters are almost the same, the transfer functions of the equivalent single power stage of the three parallelconnected boost converters can be employed [14]. As in the case of the current control loop, a PI controller is also employed.…”

“…Above all, the hybridization of mid-and heavy-sized vehicles has progressed, resulting in better fuel economy and higher performance [10]. Thus, there are many studies to improve the power and energy ratings of hybrid components such as the traction motor and the primary and secondary power sources, as well as studies aimed at new designs of these [11][12][13][14][15][16]. In particular, there has been research related to secondary sources that efficiently utilize multiple energy storage system (ESS) such as the battery and ultra-capacitor [17][18][19].…”

-Series hybrid electric vehicles (SHEVs) having multiple power sources such as an enginegenerator (EnGen), a battery, and an ultra-capacitor require a power control unit with high power density and reliable control operation. However, manufacturing using separate individual power converters has the disadvantage of low power density and requires a large number of power and signal cable wires. It is also difficult to implement the optimal power distribution and fault management algorithm because of the communication delay between the units. In order to address these concerns, this approach presents a design methodology and a power control algorithm of an integrated power converter for the SHEVs powered by multiple power sources. In this work, the design methodology of the integrated power control unit (IPCU) is firstly elaborately described, and then efficient and reliable power distribution algorithms are proposed. The design works are verified with product-level and vehicle-level performance experiments on a 10-ton SHEV.

In general, the brushless wound rotor hybrid excitation synchronous generator (HESG) needs a separate exciter. In this paper, a novel integrated brushless excitation HESG (IBE HESG) is developed by integrating the excitation section into the iron core of wound rotor HESG. Compared with the conventional brushless excitation method, the axial length of IBE HESG is shorter and original topology of wound rotor generator is not changed. The excitation section has two sets of windings: stator excitation windings and rotor armature windings. The stator excitation windings are installed in the stator slots evenly. The static excitation field is established by DC excitation current of stator excitation windings. The rotor armature windings are buried in the rotor armature slots around the rotor. The static excitation field induce the voltage in the three-phase rotor armature windings and supplies the DC current to rotor excitation windings through a rotating rectifier on the rotor. The magnetic field distribution is analyzed by frozen permeability method to decouple the multi magnetic circuits. Also, the influencing factors of excitation efficiency are studied and the parameters of IBE HESG are obtained to achieve the reasonable excitation characteristic. Finally, the theoretical analysis is confirmed by the experiments on a 1.5kVA/50Hz prototype generator. The results show that the output power can be regulated over a wide range.

“…Its power density is greatly improved, but the structure is quite complicated and not easy to manufacture. In [7], a brushless claw-pole double-rotor machine is proposed. The claw poles are separated from the stator and fixed on the outer rotor which is made of nonmagnetic and nonconductive material.…”

Abstract:A new type of permanent magnet (PM) brushless claw pole motor (CPM) with soft magnetic composite (SMC) core is designed and analyzed in this paper. The PMs are mounted on the claw pole surface, and the three-phase stator windings are fed by variable-frequency three-phase AC currents. The advantages of the proposed CPM are that the slip rings on the rotor are cast off and it can achieve the efficiency improvement and higher power density. The effects of the claw-pole structure parameters, the air-gap length, and the PM thinner parameter of the proposed CPM on the output torque are investigated by using three-dimensional time-stepping finite element method (3D TS-FEM). The optimal rotor structure of the proposed CPM is obtained by using the response surface methodology (RSM) and the particle swarm optimization (PSO) method and the comparison of full-load performances of the proposed CPM with different material cores (SMC and silicon steel) is analyzed.Keywords: PM brushless rotor claw pole motor; 3D finite element method (3D FEM); parameters optimization; response surface methodology (RSM); particle swarm optimization (PSO) method; soft magnetic composite (SMC)
