    摘要: A power converting apparatus includes a main inverter having a high-voltage DC power supply that operates at a low frequency employing SiC MOSFETs having a high withstand voltage exceeding 600 V and a sub-inverter having a low-voltage capacitor that operates through high-frequency PWM employing Si MOSFETs having a low withstand voltage. With AC sides of the main inverter and the sub-inverter connected in series, the power converting apparatus outputs AC power having a prescribed voltage waveform by adding voltages individually generated by the main inverter and the sub-inverter. Specifically, the SiC MOSFETs are used only in the main inverter of which devices are required to have a high withstand voltage and the Si MOSFETs are used in the sub-inverter of which devices may have a relatively low withstand voltage, whereby conduction loss is reduced with an inexpensive circuit configuration.

    摘要: A bicycle part comprises a tubular bicycle member elongated in a first direction and having a partition forming an interior partitioned chamber that is elongated in the first direction. The bicycle member does not form an opening extending along the entire length of the partitioned chamber that exposes the partitioned chamber, but does include an insertion opening for inserting an elongated member into the partitioned chamber.
