This paper presents the design of a power converter for electric vehicle (EV) applications energized by Li-ion battery (LiB) and supercapacitor (SC). The combination of these energy sources is a good solution for better performances of the EV. A single non-isolated bi-directional converter is proposed in order to get the lowest loss, weight and cost of total electric vehicle applications perspective. The battery voltage represents bus voltage of the power supply system connecting to the load. To control the dynamic of converter, state space averaging technique and power equation linearization are employed to get the transfer function for designing the PI controllers. In order to get the fast response of SC power energizing, the cascade controller is implemented to control current and SC voltage. MATLAB simulation is successfully verified the proposed power converter topology, configuration and controller design for EV. The result shows the capability to settling supply a significant amount of power for step load change within few milliseconds. Sudden load power demand can be drawn from SC. This can reduce the stress of battery as in case of the pure battery power supply system.

In order to achieve higher fuel efficiency and better ride comfort, this paper introduces a shock absorber system including Mechanical-Motion-Rectifier (MMR), power converter and its current/force tracking (ICFT) controller. MMR based shock absorbers has the benefit of higher efficiency and better mechanical reliability than conventional regenerative shock absorbers. However, the one-way clutches and inertia in MMR induce disengagement between input shaft and generator. This nonlinear behavior makes the input current/force of MMR uncontrollable with conventional feedback controller design. To solve this problem, this paper presents an input current/force tracking (ICFT) controller for MMR based suspension system. By adding additional control laws to the conventional controller, ICFT controller successfully solves the nonlinearity problem during MMR control. This ICFT controller is tested by tracking the reference force from skyhook control to improve ride comfort. The vehicle body displacement is simulated under specified speedbump. By using this ICFT controller, the simulation result show displacement error between skyhook and ICFT-MMR is within 5% and its total harvested energy is 56 joules, as 56 W of average input power. Equivalent circuits used for circuit simulation are proved to have identical performances as mechanical models.

The motor speed of a buck power converter and DC motor coupled system is controlled by means of a quasi-sliding scheme. The fixed point inducting control technique and the zero average dynamics strategy are used in the controller design. To estimate the load and friction torques an online estimator, computed by the least mean squares method, is used. The control scheme is tested in a rapid control prototyping system which is based on digital signal processing for a dSPACE platform. The closed loop system exhibits adequate performance, and experimental and simulation results match.
