Power converter and non-transitory computer readable medium

A non-transitory computer readable medium storing a computer program product comprising instructions configured to, when executed by a processor, cause the processor to:

• determine whether to set a connection state between a first power storage unit and a second power storage unit to a series connection or a motor-via connection, the motor-via connection being a state in which a positive terminal of the second power storage unit or a negative terminal of the first power storage is connected to a high-potential electrical path or a low-potential electrical path via a motor-side electrical path, an armature winding, and an inverter, the first power storage unit and the second power storage unit included in a power converter;
• and
• turn on an inter-storage switch and turn off a bypass switch, on a condition that the processor determines to set the connection state between the first power storage unit and the second power storage unit to the series connection, the inter-storage switch and the bypass switch included in the power converter, wherein
• the power converter includes:
• the high-potential electrical path electrically connected to the positive terminal of the first power storage unit;
• the low-potential electrical path electrically connected to the negative terminal of the second power storage unit;
• the inverter having
• an upper-arm switch electrically connected to the high-potential electrical path, and
• a lower-arm switch electrically connected to the low-potential electrical path;
• a motor having an armature winding electrically connected to a connection point between the upper-arm switch and the lower-arm switch via a conductive member;
• the inter-storage switch located at an inter-storage electrical path that electrically connects the negative terminal of the first power storage unit to the positive terminal of the second power storage unit;
• and
• the bypass switch either
• electrically connecting the negative terminal of the first power storage unit to the negative terminal of the second power storage unit, or
• electrically connecting the positive terminal of the first power storage unit to the positive terminal of the second power storage unit;
• and
• the motor-side electrical path electrically connecting the armature winding to a section of the inter-storage electrical path between the inter-storage switch and either the first power storage unit or the second power storage unit.
