Classification: CPC H | IPC H

Claim 9:
10. The drive system according to claim 9, comprising:
a) a bidirectional bridge connected to a power source having a constant voltage VB and being adapted to operate as a rectifier to one direction or as an inverter to the opposite direction;
b) the up/down DC-DC converter connected to said bidirectional bridge;
c) the controlled inverter comprising a plurality of bridges, each of which distributing an input voltage Vin to a corresponding coil of said motor;, wherein, the controller is adapted to:
d) calculate phase difference Δφ that corresponds to each value of power P and generate appropriate signals to the gates of said plurality of bridges;
e) push more power into said bidirectional bridge upon detecting that voltage VB decreases, and to return power into said power source upon detecting that voltage VB increases.
