Abstract: A hybrid converter is provided to improve resolution of an output voltage by varying a firing angle of an auxiliary converter. A main converter(110) includes a pair of internal converters(111,112). A transformed voltage with a transformation ratio of 1:pN and 1:pݻ3N is inputted into the pair of internal converters of a main converter. An auxiliary converter(120) includes the pair of converters(121,122). The transformed voltage with the transformation ratio of 1:sN and 1:sݻ3N is inputted into the pair of internal converters of the auxiliary converter. The main converter is connected in series with the auxiliary converter. The internal converter of the main converter is comprised of a diode bridge. The internal converter of the auxiliary converter is comprised of a thyristor bridge.

Abstract: An incubator having multiple cell culture system is provided to emit light of different wavelength in each cell culture system and study cell culture and differentiation state. An incubator having multiple cell culture system comprises an incubator(10), plural cell culture system(100), and central control unit(20). The incubator provides the cell culture condition. The plural cell culture system is contained inside incubator and a sample is cultured and differentiated therein. The central control unit controls the incubator and cell culture system. The cell culture system comprises a case, sample placing unit and light irradiating unit(400). The case forms a dark room of regular volume. The sample placing unit is placed in plural layers inside the case. The light irradiating unit is installed inside the case and irradiates the light to the sample placing unit. The case comprises light mounting plat, both sides board and front plate.
