What is the difference among the A-, B- and C-connections, and that among their roles?
Those connections look like as shown in the figure below.
The A-connection is capable of treating AC and DC load currents, and the B- and C-connections are capable of treating a DC load current, respectively. As the C-connection has MOSFETs connected in parallel, it is capable of treating the DC load current twice greater than the A-connection.
