Title:
POWER SUPPLY DEVICE AND METHOD FOR CONTROLLING POWER SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2010183769
Kind Code:
A
Abstract:
To suppress an increase in loss due to a charge/discharge current of a capacitor provided in a power conversion device, even when a motor frequently repeats a power-running/regeneration state.
When a capacitor temperature Tc is larger than a first temperature determination value Tcth 1, a power supply control part 43 sets a control request flag Freq to "1". As a result, when an operation is shifted from the regeneration state to the power-running state, the power supply control part 43 connects first and second power supplies in series.
