Abstract
The present invention relates generally to tuning the flow of cooling air across converter and inverter heat sinks in a motor drive system. More specifically, present techniques relate to motor drive duct systems having parallel cooling air duct channels dedicated to providing cooling air for a converter heat sink and an inverter heat sink, respectively. In particular, a first duct channel through an inverter duct and a converter duct is dedicated to providing cooling air to the converter heat sink without cooling the inverter heat sink, whereas a second duct channel through the inverter duct and the converter duct is dedicated to providing cooling air to the inverter heat sink without cooling the converter heat sink.
