Claims8
A power supply including an inductance and a capacitance connected in series circuit to receive current from a source thereof;
- a junction in said series circuit between said inductance and said capacitance;
- first switch means which can be turned on to enable current to flow from said source through said inductance and capacitance;
- second switch means which can be turned on to provide for the flow of current from said source in a path in parallel with said capacitance;
- control means causing said first and second switch means to be on simultaneously for predetermined periods;
- a transformer primary with a first and second end and a center tap, said center tap being connected to said junction;
- third switching means connected to provide a path for current flow from said first end of said primary when turned on;
- said second switching means providing a path for current flow from said second end of said primary when turned on;
- and said control means turning said second and third switching means on alternately.
