摘要
the present invention includes two power semiconductor switches using pulse width modulation (PWM: Pulse Width Modulation, or less, PWM 'referred to) boost-buck (Boost-Buck) exchange of AC (Alternating Current) -AC power converter (Power relates to the Converter) ; The present invention is a single or multiple phase (Phase). voltage (Alternating Voltage) to supply power source for supplying a load; Inductor unit or a power source side comprises a plurality of inductors (Inductor) connected in series with the power source supply on, receives the energy (Energy) from the supply power source to pass to the accumulation; One or a plurality of capacitors comprising (Capacitor) connected in series with the inductor unit on the power source side, charge accumulation capacitor section to pass to the power source side receives energy from the inductor section; Includes one or a plurality of charged capacitors and inductors connected in series on the part of, the load inductor section that receives the transmission by accumulating energy from the charging capacitor section; Connected by one or a number of series with the load unit on the load-side inductor section by receiving the energy to the output load voltage; A switch including a diode bridge (Diode Bridge) and one of the power semiconductor switch (Power Semiconductor Switch), the power side portion and the inductor between capacitor charging unit charging the power side portion and the capacitor portion and the inductor is connected in parallel to one or more of the phase paragraph (Short) or to the first switch unit to open (Open); And a switch including a diode bridge and a power semiconductor switch, charging the capacitor portion and the load-side inductor unit connected between the charge capacitor portion and the load side in parallel with the short inductor portions of one or more phase (Short) or to open ( Open) PWM boost using two of the second power semiconductor switch comprising a switch - to provide an AC-AC power converter, a buck ; According to the present invention, a plurality of power semiconductors; be able to solve the problems that may arise in sync with each switch to switch, as well as PWM Boost-Buck AC-AC power converter simplifies the configuration, it is possible to reduce the size of
