Basic Features

Following the invention of resonant power converters, lots of new topologies with significant improvements considering increase of efficiency and power density are arising. The main differences are related to the configuration of the resonant tank structure. In this paper, LCCT topology is proposed, while main aim is focused on the application of the modular architecture of power supply (MAPS) systems. Initially, principal analysis is given which describes basic features and components selection of LCCT resonant converter. After principal analysis, the application is oriented for above mentioned modular architecture of power supply, where more than one LCCT converter operated simultaneously is considered. The main asset within the presented system investigation is the proposal for the control strategy of the modular power supply system. Instead of the requirement on the most efficient operation within the whole operational power range of MAPS, the proposal for control strategy is given, while it is expected that each module of MAPS will be loaded evenly. The control strategy is based on the digital control, whereby sequential switching of the individual power stages is autonomous based on the information’s of the actual power load. Presented solution gives improvements of the parameters where extended range of input voltage, extended range of output power, flat characteristic of efficiency, and lower ripple current and/or voltage will be required.

Hysteresis Characteristics

A control strategy for pneumatic ABS(Anti-lock Braking System) of commercial vehicle has been developed and validated by combining with Trucksim simulation software and by using hardware-in-the-loop test bench for hysteresis characteristics compensation. The test results show that the ABS control strategy satisfies the control requirements for system hysteresis characteristics, and improve the performance of pneumatic ABS system for commercial vehicle effectively, thus vehicle active safety is increased.

Loop Control

In this paper, an open-loop control strategy is proposed for maneuvering the angular motion of a Digital Micromirror Device (DMD). The control law is based on a micromirror model that accounts for both bending and torsion motions. The model characterizes two DMD configurations: with and without contact with the substrate. The device is actuated using an electrostatic field which is a nonlinear function of the states and input voltage. The proposed control strategy is a Zero Vibration (ZV) shaper. It overshoots the DMD to its desired final angle by appropriately varying two independent input voltages. Actuating voltages and switching times are determined to maneuver the DMD from −10° to +10° tilt angles while reducing the residual vibrations.
