Claim 6:
7. The method according to claim 1, comprising:
providing an up/down DC-DC converter for converting said feeding power to said input voltages according to a command signal provided by said controller,, said controller is adapted to:
sample the instantaneous angle of the rotor of said BLDC motor;
sample the input voltage Vin and a current I of each phase to obtain the input power P; and
for each Vin, calculate the phase difference Δφ value that corresponds said input power P and feed said phase difference value to said up/down DC-DC converter, thereby causing said up/down DC-DC converter to apply each Vin to its corresponding coil at a specific timing for obtaining an optimal match between said each Vin and the current that is being built up in said corresponding coil.
