    摘要： A pulse width modulation resonance converter is provided that includes a transformer and a switching unit including first to fourth switches electrically connected to a primary coil of the transformer and configured to convert a DC voltage into an AC voltage by a switching operation of the first to fourth switches in which each switch is switched from an off state to an on state when a voltage difference between both ends is about 0. Additionally, a rectifying unit includes an output capacitor, first to fourth diodes electrically connected to a secondary coil of the transformer, and a resonance tank having a resonance capacitor and a resonance inductor which are electrically connected to the secondary coil of the transformer. The plurality of switches connected to the primary side of the transformer perform the zero-voltage switching using the magnetized inductance of the primary side to minimize the switching loss.

    摘要： A lubrication system of a transmission includes a plurality of oil passages formed in an upper portion of a transmission case and supplied with churning oil, a plurality of oil outlets branched from respective oil passages formed in the transmission case and allowing oil supplied from the oil passages to free-fall, and an oil collecting portion formed at an interior of the case wall between the gear case and the motor case. In particular, the oil collecting portion collects oil free-falling from at least one oil outlet branched from at least one oil passage at the gear case, through a through-hole formed at a case wall of the gear case, and then supplies the collected oil to an exterior lubrication portion.
