Power converter

A method, comprising:

• regulating an output current (11) of a first converter stage (1) and regulating an output voltage (Vo) at the output of a second converter stage (2) by a link circuit (3) in a power converter,
• wherein the power converter comprises:
• a first converter stage (1) configured to receive three alternating input voltages (Va, Vb, Vc) at input nodes (11a, 11b, 11c) and provide a pulsating output voltage (V1) at an output (12, 13);
• a second converter stage (2) configured to receive an input voltage (V2) at an input (22, 23) and provide an output voltage (Vo) at an output (24, 25);
• and
• a link circuit (3) comprising a link (31, 32) coupled between the output (12, 13) of the first converter stage (1) and the input (22, 23) of the second converter stage (2), and supply nodes (33, 34) coupled to the second converter stage (2).

A control circuit (66) configured to control operation of a link circuit (3) in a power converter such that the link circuit (3) regulates an output current (11) of a first converter stage (1) and regulates an output voltage (Vo) at an output of a second converter stage (2),

• wherein the power converter, comprising:
• the first converter stage (1) configured to receive three alternating input voltages (Va, Vb, Vc) at input nodes (11a, 11b, 11c) and provide a pulsating output voltage (V1) at an output (12, 13);
• the second converter stage (2) configured to receive an input voltage (V2) at an input (22, 23) and provide the output voltage (Vo) at the output (24, 25);
• and
• the link circuit (3) comprising a link (31, 32) coupled between the output (12, 13) of the first converter stage (1) and the input (22, 23) of the second converter stage (2), and supply nodes (33, 34) coupled to the second converter stage (2).
