Based on the analysis of high-gain tri-state current source inverter (CSI) and passive inductor network on DC-side, this paper presents parameters optimal design method and introduces a special space vector modulation (SVM), which is applied to the proposed high gain CSI. Besides, a dual-loop control strategy is formulated by analyzing its outer-loop and inner-loop controllers in grid-connected mode. Simulation results in MATLAB prove that novel CSI with proposed control strategy and parameters optimization design can realize high-gain output and steady operation.

It’s important to improve the efficiency at partial load operation of middle capacity in order to provide an energy-saving air conditioner. To improve this efficiency of operation at partial load, high winding motors are used for compressors and DC voltages are boosted. However, energy loss caused by the boost circuit is an issue at maximum capacity load. We accomplished the improvement of efficiency at all operation capacity load by technologies of efficiently driving SJMOSFET.

To integrate PV, storage, utility grid and loads in dc residence efficiently, a novel partially isolated multiport converter named PIMPC as well as a multi-objective control strategy are proposed. Multiple control objectives can be realized through the proposed control strategy simultaneously, for instance, maximizing PV utilization, avoiding overcharge or overdischarge of storage and regulating all supplied voltages etc.. Finally, simulation results in Matlab validate the proposed topology and control strategy.

This paper present features of a silicon carbide (SiC) power module (SiC J1-series) dedicated for electric vehicle (EV) and hybrid electric vehicle (HEV) power train. To compare a Silicon power module and a SiC power module, loss simulation was performed with both modules having the same package and the same rating chips (300A/1200V). As a result, the power loss of the SiC power module has been reduced by 62% compared with the Si power module.
