Claim 1:
2. The power supply circuit of claim 1, further composing:
a second leg having a second lower-arm freewheeling diode and a second upper-arm switching element connected in series to the second lower-arm freewheeling diode via a cathode, the second leg being connected to the DC voltage source; and
a third leg having a third upper-arm freewheeling diode and a third lower-arm switching element connected in series to the third upper-arm freewheeling diode via an anode, the third leg being connected to the DC voltage source,
the first actuator coil being connected between
the midpoint between the first upper-arm switching element and the first lower-arm switching element and
a midpoint between the second upper-arm switching element and the second lower-arm freewheeling diode, and

the second actuator coil being connected between
the midpoint between the first upper-arm switching element and the first lower-arm switching element and
a midpoint between the third upper-arm freewheeling diode and the third lower-arm switching element.
