• DC to DC power converter topologies that are suitable for high-density, high- power supplies are presented. Topological variations on the basic inverse dual converter (IDC) circuit, such as the coupled transformer and the multiphase and multipulse derivation of the single-phase IDC, are analyzed, and simulation results are discussed. The topologies have most of the IDC features, such as buck-boost operation, bidirectional power processing, capacitive commutation for switches, and unlimited high-power capability.

• This paper explores a family of integrated multiport converters using three- switch which can provide single-input dual-output (SIDO) or dual-input single- output (DISO) with bidirectional power flow between any two ports. The concept can be extended to the n-switch converters to achieve more inputs and/or outputs. The proposed converters can be applied to interfacing sources, loads and storage elements having different voltage levels in applications such as dc nanogrids, electric vehicle, multiport power supplies, distributed generation systems. Various topological configurations of the integrated multiport n-switch converter are investigated. The operating principles and PWM control strategy of these converters are analyzed in detail. A universalized hardware prototype is built, experimental results are provided for verification.

• A consolidation of existing as well as new configurations of voltage source power converters (VSCs) using gate turn-offs (GTOs) or a combination of GTOs and thyristors is considered. These VSCs are single-phase AC-DC current- controlled boost-type power converters with bidirectional power-handling capability. Both two-level and three-level power converters are presented along with a definitive classification. Experimental results are provided on a selective basis, confirming a 360/spl deg/ power angle range of the power converters.

• A rectifier system having a DC voltage step-up and step-down characteristic is treated. The system consists of a PWM voltage source rectifier and a DC-to-DC buck converter connected in cascade. Theoretically, the system can produce a DC output voltage ranging from zero volts to infinity and a sinusoidal AC input current, and the displacement power factor can be kept at unity. The system can perform bidirectional power flow. Control strategy based on a sinusoidal internal model is proposed. Two PS regulators and two PI regulators for each control object is used. Experimental results confirm the validity of the proposed control system.

• While the matrix converter has many advantages that include bidirectional power flow, a size reduction, a long lifetime, and sinusoidal input currents, it is vulnerable to the input voltage disturbances, because it directly exchanges the input voltage to the output voltage. The instantaneous effective power control (IEPC) method has been proposed to compensate the input voltage disturbances, in which the instantaneous effective power is kept constant by controlling input current. However, to date, no method has been proposed to maintain the stability of the system with the IEPC. The purpose of this paper is to propose a method to control the stability of the system with IEPC. First, this paper explains the IEPC theoretically. Next, a model of the system with the IEPC is developed, and stability analyses are conducted. Then, based on the results of the analyses, a stability control method for the system with the IEPC is proposed. Furthermore, the validities of the proposed method are demonstrated by simulation and experiments. Finally, a restart performance of the system after momentary power interruption is discussed. Because the IEPC does not need phase-locked-loop to detect the phase angle of the input voltage, fast restart is expected

• A broadband GaAs bidirectional distributed amplifier (BDA) designed using$G_{m}$-bandwidth ($G_{m}$-BW) extension technique is presented in this letter. A$G_{m}$-BW extension configuration is investigated, and utilized in the gain stage of the BDA for enhancing gain and bandwidth performance. The isolation between forward path and reverse path is improved by using adaptive load network. The BDA exhibits small-signal gains of higher than 14.4 dB with a 3 dB bandwidth from 1.6 to 23.6 GHz. The measured output 1 dB gain compression point$(\mathrm{OP}_{1\ \mathrm{dB}})$and output third-order intercept point$(\mathrm{OIP}_{3})$over 3 dB bandwidth are higher than$-$7 and 1 dBm, respectively.

• Two new soft-switching DC-DC power converters, with the capabilities of bidirectional power flow and soft-switching (either zero-voltage transition or zero-current transition) are developed for DC motor drives. The proposed bidirectional zero-voltage-transition power converter possesses the definite advantages that both main transistors and rectifiers can switch with zero- voltage switching (ZVS) and unity device stresses during both motoring and regenerating modes of operation, while both the main and auxiliary switches of the bidirectional zero-current-transition power converter can operate with zero-current switching (ZCS) and minimum voltage/current stress. These converters are particularly useful for DC traction systems in which both motoring and regenerative braking are desired to have high efficiency.

• Zeta mode three-level AC/AC converter can realize three-level voltage before output filter, which can get a better spectrum and reduce bulk of the filter. Compared with non-isolation and low or middle frequency isolation AC/DC/AC converters, it is single stage. And compared with Buck non-isolation AC/AC converter which can only realize buck output voltage, it can realize buck and boost output voltage. Zeta mode three-level AC/AC converter has four operation states in one period of input voltage and three different operation modes in one switching period. The non-complementary control strategy proposed makes the converter switch smoothly between different operation modes without any voltage spike. It also realizes non-complementary control in bidirectional power flow. As a result, the converter is suitable to different kinds of loads. It doesn't need to think over dead-time and its bad effects.

• A robust sliding-mode controller, suitable for the output voltage control of voltage-sourced unity-power-factor three-phase pulsewidth modulation (PWM) rectifiers, presenting no steady-state errors, is described. This "just-in- time" switching controller controls the output voltage and the line input currents, while providing bidirectional power flow, near-unity-power-factor operation, low harmonic content, fast dynamic response of the output voltage, and minimum switching frequency due to a new /spl alpha/-/spl beta/ space- vector current regulator. The voltage controller performance is compared with the behavior of the conventional proportional integral output voltage control, aided by PWM current-mode modulators, and with the nonrobust fast and slow manifold sliding-mode approach. The comparison shows that the proposed controller confers faster dynamics and does not present steady-state errors. Test results confirm that the performance of the controller is independent of system parameters and load and exceeds the performance of existing hysteretic current-mode control systems.
