Claim 1:
2. The energy conversion device according to claim 1, wherein
when L1 sets of the winding units of the L sets of the winding units operate in the at least two sets of heating circuits, the L1 sets of the winding units respectively correspond to L1 resultant current vectors, and form, L
   ⁢
   1
  
  2, pairs of the resultant current vectors; amplitudes of two resultant current vectors of each pair of the resultant current vectors are equal; each pair of the resultant current vectors are symmetrical with respect to a direct axis of the synchronous rotating reference frame; L≥L1≥2; and L1 is an even number.
