REGENERATIVE ABSORPTION SYSTEM OF INVERTER FOR HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a regenerative absorption system of a plurality of inverters for a hybrid vehicle capable of avoiding the biased regenerative absorption operations of the plurality of inverters.

SOLUTION: This regenerative absorption system controls the plurality of inverters 5 supplied with AC power converted from DC power supplied from a battery 15 to a plurality of running motors 10 using a controller 8. Each of the inverters 5 includes a regenerative absorption resistor 23 for absorbing regenerative power and regenerative absorption drive means 24, 25 for operating the regenerative absorption resistor 23 when regenerative power is large. The controller 8 detects the voltage of a main power line 30 which connects the battery 15 with the plurality of inverters 5, transmits a regenerative absorption instruction to the regenerative absorption drive means 25 if the detected voltage level exceeds a predetermined one, and operates the regenerative absorption resistor 23 with the regenerative absorption drive means 24.
