<p><P>PROBLEM TO BE SOLVED: To provide a voltage converter which is satisfactory in controllability, concerning a voltage converter which performs bidirectional voltage conversion between two power sources, and an automobile which mounts it. <P>SOLUTION: The voltage converter 10 is equipped with NPN transistors Q1-Q4, diodes D1-D4, a smoothing reactor L1, and auxiliary circuits H1 and H2. The auxiliary circuits H1 and H2 are connected in parallel with the smoothing reactor L1 between a node N1 and a node N2. The auxiliary circuit H1 includes a shock absorbing capacitor C3, a diode D5, and an NPN transistor Q5 connected in series. Moreover, the auxiliary circuit H1 includes a reactor L2 for resonance and a diode D7 connected in series between a node N3 and a negative bus LN3. The auxiliary circuit H2 includes a shock absorbing capacitor C4, a diode D8, and an NPN transistor Q6 connected in series. Moreover, the auxiliary circuit H2 includes a reactor L3 and a diode D10 connected in series between a node N4 and a negative bus LN3. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
