So I am doing unipolar switching in PSIM, and have an H bridge with an RL load in the center. When I measure the load voltage, I get only the top half of the "sine wave". Can someone take a look at my circuit and tell me where I am going wrong? Vtop and Vbottom are the outputs of the top and bottom comparators, respectively.
for links use the actual at sign Shift+2, i'm not sure why its not posting correctly
