An SST generally contains a high-frequency transformer inside the DC-to-DC converter or AC-to-AC converter, which transmits power and offers electric isolation.
The output stage is connected to the previous one using a broadband high-frequency transformer similar to T1 (not shown in the diagram).
With a significant advance of MOS-gate power semiconductor devices, a variety of DC-DC power converters with a high-frequency transformer link have been widely studied and put into practice so far [1]-[5].
In a practical system, the leakage inductance of the high-frequency transformer should be minimized to prevent the so-called spot heating on the transformer.
This methodology examines the electric field distribution to estimate the values of capacitance of a surface discharge cell and proposes a method for designing high-frequency transformer, which allows the system to operate in a state of resonance.
Most high-power DC-to-AC converters use an H-bridge configuration (four power devices) for exciting the high-frequency transformer. The H-bridge is controlled with pulse-width modulation (PWM) or other modulation strategies to produce a voltage of limited pulse width or amplitude.
