    Abstract: The present invention relates to a foam polystyrene-based bead. The foam polystyrene-based bead includes: a core containing a styrene-based resin, a char-generating thermoplastic resin, and an inorganic foam; and a skin disposed on the surface of the core, wherein the skin contains a resin of which the glass transition temperature is below around 120°C. Here, the foam is contained in the core or skin. The core may further include a carbon filter. The foam manufactured from the flame retardant foam polystyrene-based bead does not conform to KS F ISO 5660-1, but is a self-extinguishing flame retardant material. Thus, the foam may have improved flameproof properties as compared to those of a flame retardant material (flame retardant 3rd degree), better thermal insulation performance, and superior mechanical strength.

    Abstract: The present invention relates to a parallel connected switching converter in which the turn-on and turn-off operations of a plurality of converters connected in parallel with each other are controlled to keep the phase difference between the converters constant. The parallel connected switching converter of the present invention includes: a first switching control unit for generating a first switching control signal for controlling the turn-on and turn-off operations of a first converter; a synchronous signal generating unit provided with a first capacitor and a second capacitor, interconnecting the first capacitor and the second capacitor in accordance with a first switching control signal output from the first switching control unit to control the voltage of the first capacitor through charge sharing between the first capacitor and the second capacitor, and generating a synchronous signal which is synchronous to the first switching control signal and having a predetermined phase difference by using the voltage of the first capacitor; and a second switching control unit for generating a second switching control signal in accordance with the synchronous signal output from the synchronous signal generating unit to control the turn-on and turn-off operations of the second converter. The parallel connected switching converter of the present invention keeps the phase difference between parallel connected converters constant by using a charge sharing scheme, and controls all of the parallel connected converters to operate in a DCM (discontinuous conduction mode), thereby being capable of preventing an increase in switching loss and switching noise caused by reverse recovery resulting from their operation in a CCM (continuous conduction mode).
