In a vehicle charging device having a second charger, the first charger has a higher output voltage and better cooling performance than the second charger,

較して、両者の温度の均一化を図ることができる。According to the present invention, when the output current is small, the first charger having the high output voltage takes charge of the output. When the output current increases, the output voltage decreases under the control of the first charger. When the output voltage of the first charger falls below the output voltage of the second charger due to a decrease in the output voltage of the first charger due to an increase in the output current, the second charger also generates an output current, and both chargers operate in parallel. Start. Also in this parallel operation, as the output voltage of the first charger decreases due to the increase of the output current, the second charger generates a corresponding output current corresponding to the output voltage equal to the output voltage of the first charger. Eventually, the first charger will operate more severely in temperature than the second charger, but since the first charger has better cooling performance than the second charger, the first charger Temperature rise can be suppressed relatively to that of the second charger, and as a result, the first charger, which has better cooling, bears a relatively large output current, so that both chargers have the same output. Compared to the case where there is a voltage, the two temperatures can be made more uniform.

後、流しても良い。There are various methods for relatively improving the cooling performance of the first charger. For example, the first charger may be arranged upstream (lower temperature side) of a cooling medium (for example, cooling air or cooling liquid), or the first charger may be fixed to a cooling fin having a larger area than the second charger. Good. Further, the cooling medium may be relatively diverted to the first charger and relatively diverted to the second charger. Further, the cooling medium may be directly supplied to the first charger, and may be supplied to the second charger after cooling other circuit devices.

This is done by changing the turns ratio of the transformer of the C converter and the inductance of the choke coil. At this time, if both chargers are formed using the same circuit components except for the circuit components for setting the output voltage value, the manufacture becomes easy. Alternatively, a charger having the same output voltage may be directly connected to one of the chargers and the other to an output line through a small resistor. As a result, the output voltages of both chargers as viewed substantially from the output line are changed when there is an output current. As a variation, the output end of the second charger may be connected to a connection point between the first charger and the electric load via an output line. As a result, the output voltage of the second charger viewed from the connection point decreases by the voltage drop corresponding to the electric resistance of the output line.
