Obtain the admittance curves around the first
resonance frequency (71 kHz) under the external resistance
load for 1 GW (almost
open) and 1 MW. Show the resonance
frequency shift and the peak broadening, then explain the
reason briefly from the physical viewpoint. |
2.
|
Calculate the output voltage under the external load
(instead of Floating Condition) from 1 kW to
1 GW under the 1 V input voltage
and the frequency (71 kHz) fixed. Draw the step-up voltage
ratio as a function of load in a log-log graph. |
3.
|
Calculate the output voltage under the external load
from 1 kW to
1 GW under the 1 V input voltage
fixed at the peak frequency. Draw the step-up voltage ratio
as a function of load in a log-log graph. |
4.
|
Calculate the output power under the external load, and
show that the maximum is obtained at the load which corresponds
to the impedance of the transformer output (Impedance
Matching). |
