Power-dense bipolar high-voltage transformer
View Patent ↗An exemplary transformer is provided for high voltage and low leakage inductance, including an outer housing, a complementary pair of iron C-sections, bobbins and Litz wire. The iron C-sections form a magnetic loop core, forming proximal and distal sides. The bobbins include outer and inner primary bobbins, as well as outer, middle and inner secondary bobbins. The inner secondary bobbin has a center gap for receiving the proximal side of the core and is disposable within the inner primary bobbin. Inner and outer primary Litz wires have rectangular cross-sections and respectively wrap around the inner and outer primary bobbins. The secondary Litz wire contiguously wraps around the secondary bobbins. The primary Litz wires connect together by a shunt. The inner primary bobbin is disposable within the middle secondary bobbin. The middle secondary bobbin is disposable within the outer primary bobbin. The outer primary bobbin is disposable within the outer secondary bobbin. The outer secondary bobbin is disposable within the housing.
1. A high voltage low leakage inductance transformer, said transformer comprising:
an outer housing;
a complementary pair of iron C-sections to form a magnetic loop core, said core forming proximal and distal sides;
outer and inner primary bobbins;
outer, middle and inner secondary bobbins, said inner secondary bobbin having a center gap for receiving said proximal side of said core and disposable within said inner primary bobbin;
inner and outer primary Litz wires having rectangular cross-sections and respectively wrap around said inner and outer primary bobbins; and
a secondary Litz wire that contiguously wraps around said secondary bobbins, wherein
said primary Litz wires connect together by a shunt,
said inner primary bobbin is disposable within said middle secondary bobbin,
said middle secondary bobbin is disposable within said outer primary bobbin,
said outer primary bobbin is disposable within said outer secondary bobbin, and
said outer secondary bobbin is disposable within said distal side of said core and said housing.
2. The transformer according to claim 1 , wherein said bobbins are composed of glass-impregnated nylon.
3. The transformer according to claim 1 , wherein said C-sections are composed of nano-crystaline amorphous iron.
4. The transformer according to claim 1 , wherein said distal side of said core is disposable within said housing.
