Planar transformer

Modern planar technologies allow providing a new quality level of exploitation and cost characteristics of power supplies and devices on the whole, which are impossible to reach if using traditional technologies.

• Small size
• Good temperature characteristics
• Low leakage inductance
• Excellent repeatability

Variants of planar transformer arrangement

	Traditional assembly.
	Transformer is "sunk" into circuit board.
	Hybrid design: transformer is partially integrated into circuit board.
	Transformer windings are placed in the card's layers, and core is integrated into the circuit board itself.

Integrated Magnetic Components

Integration of several power components (transformers, inductances, capacitors) on one magnetic core allows decreasing significantly the weight and size of feed elements.

Benefits of using planar technologies in sources of voltage transducer

• Wide range of possible power 1 MW: 1500 W and working frequency 10 GHz - 3 MHz;
• High quality, cost and exploitation requirements by means of optimization of magnetic element structure and voltage transducer on the whole;
• Absence of redundancy and necessity of additional modifications (in comparison to universal modules);
• Lower feed system cost when mass produced;
• Smaller size and weight of final device.

Technology drawbacks

• High cost when single produced.
