Black - General Circuit:
Connections, passive components, diodes, and other circuitry.
Cyan - Power Supply Circuit:
DC Supply be it battery, rectified AC source, switch mode supply etc.
Green - Tank Circuit:
Resonant Circuit - Lowest Z (impedance) at resonant frequency.
These are tuned resonant circuits with specific values of L or C
LC (Ideal) Inductive Capacitive.
RLC (Actual) Resistive Inductive Capacitive.
Red - Switching Circuit:
Switching Device. (Fast Switching Semiconductor Device is assumed)
Possibly: MOSFET's, IGBT, BJT, Tube, Contactor, Relay or Spark Gap etc.
No arrows indicated on switch's - assumed bidirectional nature.
For unidirectional devices freewheeling diodes in anti-parallel must be included.
Figure 1 - Off-Line (right off the lines or mains) Topology
Similar to a DC resonant spark gap coil. With the charging choke and diode removed the circuit is very similar to a typical spark gap coil layout however most use an AC source not a DC source. A diode in anti parallel with the charging choke is recommended.
