Abstract
Provided herein is an inverter module that can include a first inverter cell and a second inverter cell, each including at least one transistor device, and a cold plate placed in contact with or proximate to the at least one transistor device. The cold plate can have a coolant channel through the cold plate. A connector can connect a coolant outlet of the cold plate of the first inverter cell to a coolant inlet of the cold plate of the second inverter cell in series, to form a continuous channel that extends from the first coolant inlet of the cold plate of the first inverter cell into the coolant channel of the cold plate of the second inverter cell. The coolant inlet of the cold plate of the first inverter cell can receive coolant fluid into the continuous channel.
