ELECTRIC VEHICLE DRIVE DC-DC CONVERTER AND ELECTRIC VEHICLE |
摘要 |
<p>An electric vehicle drive DC-DC converter and an electric vehicle are provided in which the electric vehicle drive DC-DC converter is constructed by connecting a plurality of DC-DC converter units in parallel, and in which a smoothing capacitor is allowed to be reduced in size thereof so that the DC-DC converter unit can be constructed in a small size, and electric power required by the electric vehicle can be coped with by only increasing the number of DC-DC converter units. Each of the DC-DC converter units includes: a coil having both ends thereof being connected to a DC power source and an electric vehicle drive source (motor); and a drive element which is connected in parallel to the electric vehicle drive source and driven in response to a signal supplied from a control circuit, the drive element having combined therewith a load current commutation diode. A single smoothing capacitor is connected in parallel to the electric vehicle drive source so that the respective drive elements of the plurality of DC-DC converter units are driven by the control circuit at different timings.</p> |
