By the usual lumped model:
C2=secondary capacitance (self-capacitance of L2 and terminal
V1=voltage in C1 (input voltage)
V2=voltage in C2 (output voltage)
Energy initially stored in the primary capacitor:
Maximum energy at the secondary capacitance:
By energy conservation, assuming low losses in the energy transfer:
But the two LC circuits are tuned to the same frequency:
