Systems and methods for reducing physical size of power converter with active filter

A multipurpose power converter system configured to provide AC power to a load of a transport climate control system, the multipurpose power converter system comprising:

• a multipurpose power converter including:
• a rectifier having a first leg, a second leg, and a third leg;
• a first switch and a second switch;
• and
• an inductor-capacitor network,
• wherein the first switch and the second switch are connected to the third leg, the second switch being between a power source and the third leg;
• the inductor-capacitor network is connected to the first switch, the first switch being between the third leg and the inductor-capacitor network;
• when the first switch is on and the second switch is off, the multipurpose power converter is configured as a single-phase AC power converter;
• and
• when the first switch is off and the second switch is on, the multipurpose power converter is configured as a three-phase AC power converter;
• a DC-link capacitor;
• and
• a controller,
• wherein the DC-link capacitor is connected to the multipurpose power converter, and
• the controller is configured to control the first switch and the second switch.

A method for controlling a multipurpose power converter for converting power for a transport climate control system, the multipurpose power converter including a rectifier having a first leg, a second leg, and a third leg;

• a first switch and a second switch;
• and an inductor-capacitor network, the first switch and the second switch are connected to the third leg, the second switch being between a power source and the third leg;
• and the inductor-capacitor network is connected to the first switch, the first switch being between the third leg and the inductor-capacitor network;
• the method comprising:
• determining that the multipurpose power converter is connected to one of a single-phase AC power source and a three-phase AC power source;
• when the multipurpose power converter is connected to a single-phase AC power source, controlling, by a controller, the first switch on and the second switch off, so that the multipurpose power converter is configured as a single-phase AC power converter;
• and
• when the multipurpose power converter is connected to a three-phase AC power source, controlling, by the controller, the first switch off and the second switch on, so that the multipurpose power converter is configured as a three-phase AC power converter.
