According to an aspect of the invention, a motor drive circuit (100, 142, 148, 156, 200, 212, 232, 238) includes a first energy storage device (102) configured to supply electrical energy, a bi-directional DC-to-DC voltage converter (106, 158, 160, 162) coupled to the first energy storage device (102), a voltage inverter (134) coupled to the bi-directional DC-to-DC voltage converter (106, 158, 160, 162), and an input device (124) configured to receive electrical energy from an external energy source (132). The motor drive circuit (100, 142, 148, 156, 200, 212, 232, 238) further includes a coupling system (116) coupled to the input device (124), to the first energy storage device (102), and to the bi-directional DC-to-DC voltage converter (106, 158, 160, 162). The coupling system (116) has a first configuration configured to transfer electrical energy to the first energy storage device (102) via the bi- directional DC-to--DC voltage converter (106, 158, 160, 162), and has a second configuration configured to transfer electrical energy from the first energy storage device (102) to the voltage inverter (134) via the bi-directional DC-to-DC voltage converter (106, 158, 160, 162).
