“…The well-known voltage-source inverter (VSI) is a buck type inverter when power flows from DC to AC and a boost type PWM rectifier when it is the other way around [6], [7]. This means the amplitude of the DC side voltage must be greater than that of the AC side.…”

In this paper, a unified control strategy using the current space vector modulation (CSVM) technique is proposed and applied to a bidirectional three-phase DC/AC converter. The operation of the converter changes with the direction of the power flow. In the charging mode, it works as a buck type rectifier; and during the discharging mode, it operates as a boost type inverter, which makes it suitable as an interface between high voltage AC grids and low voltage energy storage devices. This topology has the following advantages: high conversion efficiency, high power factor at the grid side, tight control of the charging current and fast transition between the charging and discharging modes. The operating principle of the mode analysis, the gate signal generation, the general control strategy and the transition from a constant current (CC) to a constant voltage (CV) in the charging mode are discussed. The proposed control strategy has been validated by simulations and experimental results obtained with a 1kW laboratory prototype using supercapacitors as an energy storage device.

Abstract. This paper presents several methods that enable the reduction of power loss in the auxiliary resonant commutated pole inverter -ARCP. Presented methods can be divided into static and dynamic ones. The static methods are related to an appropriate design of the inverter, whereas dynamic ones to advanced control of the power transistors. A variety of design and control methods are presented together with their advantages and disadvantages. The new control method of the current in the resonant branch is described. The main benefits of the proposed extended control method and their constrains are shown.

“…To solve these problems and maintain a high frequency, soft switching is one of the best options. A variety of soft switching techniques have been proposed for inverter applications [2]- [14]. They can be classified into three groups: load resonant [2], [3], resonant link [4]- [9], and resonant transition [10]- [14].…”

“…A variety of soft switching techniques have been proposed for inverter applications [2]- [14]. They can be classified into three groups: load resonant [2], [3], resonant link [4]- [9], and resonant transition [10]- [14]. However, most of these require special inverter topologies, auxiliary resonant components, additional switches, and complex control algorithms, resulting in size and cost increases in inverter systems.…”

This paper proposes a Boundary Current Mode (BCM) control scheme to realize soft switching on a conventional single phase full bridge DC/AC inverter. This technique with the advantages of no auxiliary components, low cost, high efficiency, and simple in control, is attractive for micro-inverter applications. The operation principle and characteristic waveforms of the proposed soft switching technique are analyzed in theory. A digital controller is provided based on that theory. To balance the requirements of efficiency, switching frequency, and inductor size, the design considerations are discussed in detail to guide in BCM inverter construction. A 150W prototype is built under these guidelines to implement the BCM control scheme. Simulation and experiment results demonstrate the feasibilities of the proposed soft switching technique.
