Toroidal Transformers is mainly used as a power transformer and isolation transformers. Toroidal transformer at home and abroad have a complete series, widely used in medical equipment, telecommunications, instrumentation, photovoltaic power generation and lighting, and so on. Ring transformer because of excellent cost performance, good output characteristics and anti-jamming capability.

Large isolation transformers power high-grade toroidal transformer can be customized power transformer contact voltage regulator

toroidal transformers is based on the choice of materials in the production, based on the actual production of the majority of the actual market because of cost pressures and competitive needs, not strictly according to industry specifications, and sometimes even jerry-building, analysis of unpredictable factors more. The first is the core material quality, many enterprises with low permeability core, trimmed and even mixed with soft iron production transformer, resulting in transformer no-load current is high, iron loss is too large, no-load fever serious; this type of transformer to reduce Cost, at the same time to cover the high iron loss caused by the voltage regulation rate is too large to significantly reduce the number of primary and secondary coil turns to reduce the way the copper loss to reduce the voltage regulation, this approach further increases the no-load Current, and no-load current is too large will directly lead to increased magnetic leakage.

toroidal transformers manufacturers problems more complex. Regular ring-type transformer core is a wide-width silicon steel band from a tight winding. Or for cost reasons, the majority of low-cost ring-type transformer with several or even dozens of silicon steel stitching, and even use the edge of the uneven scraping, winding machine after the car flat, the ring transformer coil package Around the core, do not do destructive anatomy difficult to find. Mechanical processing of silicon material on the lattice, the insulation between adjacent silicon steel has serious damage, such ring-shaped transformer regardless of performance or leakage magnetic properties will be greatly reduced, even after annealing can not make up for serious quality defects .

Another need to pay attention to the interference source for the rectifier circuit. Filter capacitor in the boot into the normal state, the charge is only concentrated in the AC peak, the charge waveform is a narrow width of the strong pulse, the greater the capacity, the greater the pulse intensity, from the electromagnetic interference point of view, the filter capacitor is not the greater the more Good, rectifier and filter capacitor wiring between the lines should be shortened, while away from the amplifier circuit, PCB space is not allowed to try to use the ground line envelope.
