Indirect matrix converter (IMC) is an alternative for ac/ac energy conversion, usually operated with a voltage stepped-down gain of only 0.866. For applications like distribution generation where voltage-boost functionality is required, the traditional style of operating the IMC is therefore not appropriate. Like most power converters, the operation of the IMC can surely be reversed to produce a boosted...
Matrix converter (MC) can be used as ac type distributed generator (DG) interface in microgrid. Reverse power flow operation of MC can be implemented to meet voltage boost requirement, where the input ac generator is connected to the converter's voltage source side and the output utility grid or load is connected to the current source side. During grid fault or intentional islanded operation, the...
Single-phase stand-alone PV system is suitable for household applications in remote area. Hybrid battery/ultra-capacitor energy storage can reduce charge and discharge cycles and avoid deep discharges of battery. This paper proposes a compact seven switches structure for stand-alone PV system, which otherwise needs nine switches configuration, inclusive of one switch for boost converter, four switches...
