Example of bobbin-less high-frequency transformer
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 -.
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.
Li, "High-frequency transformer
isolated bidirectional DC-DC converter modules with high efficiency over wide load range for 20 kVA solid-state transformer", IEEE Trans.
It deals about pulse generator, resonant circuit with high-frequency transformer
and rectifier with capacitive filter.
Based on the component, the market is segmented into converters, switches, high-frequency transformers
, and others.
This book looks at design, manufacture, and debugging, including peripheral component characteristics, designing power factor correction circuits, and high-frequency transformers
. Readers must be extremely comfortable with the book's abundant engineering equations and complex circuit diagrams.
As an example of the increased diversification this brings to Bel's product line, the Signal Transformer acquisition adds a new market - custom and high-frequency transformers
- and thousands of new customers to Bel's business.
