Apparatus for transferring energy using onboard power electronics with high-frequency transformer isolation and method of manufacturing same

摘要

An apparatus for transferring energy using onboard power electronics with high-frequency transformer isolation includes a power electronic drive circuit (10,134,136,142,174,178) comprises a dc bus (52,176) and a first energy storage device (12) coupled to the dc bus (52,176). A first bi-directional dc-to-ac voltage inverter (54,144) is coupled to the first energy storage device (12) and to the dc bus (52,176), and a first electromechanical device (74,144) coupled to the first bi-directional dc-to-ac voltage inverter (54,144). A charging system (92) coupled to the dc bus (52,176) via a charge bus (94) comprises a receptacle (120) configured to mate with a connector (126) coupled to a voltage source (132) external to the power electronic drive circuit (10,134,136,142,174,178) and an isolation transformer (112) configured to electrically isolate the charge bus (94) from the receptacle (120). A controller (34,114) configured to cause the charging system (92) to supply a charging voltage to the dc bus (52,176) based on a voltage received from the voltage source (132) external to the power electronic drive circuit (10,134,136,142,174,178).
