What is resonant transformer?

What is resonant transformer?

A resonant transformer is a transformer in which one or both windings has a capacitor across it and functions as a tuned circuit. Used at radio frequencies, resonant transformers can function as high Q factor bandpass filters.

What are the uses of resonant transformer?

Resonant transformers are widely used in radio circuits as bandpass filters, and in switching power supplies.

What are the electrical components used to realize the energy transfer in inductive coupling?

In inductive coupling (electromagnetic induction or inductive power transfer, IPT), power is transferred between coils of wire by a magnetic field. The transmitter and receiver coils together form a transformer (see diagram).

What are advantages of resonant transformers?

RESONANT TRANSFORMERS • The advantages of this principle are: – Gives an output of pure sine wave – Power requirements are less (5 to 10% of total kVA required) – No high-power arcing and heavy current surges occur if the test object fails (since resonance ceases at the failure of the test object) – Cascading is …

How does 110V transformer work?

A transformer (typically bright yellow) is used to convert a typical ‘household’ 240V power supply to 110V, with yet more bright yellow leads running out from the transformer to your equipment. 110V site transformers are centre tapped, which means that the 110V output is actually 2 x 55V.

What is output waveform of resonant transformer?

In testing with a resonant transformer, the output voltage is. Rectangular wave. Triangular wave.

Can electricity be transmitted without wires?

Wireless power transfer is the transmission of electrical energy without wires as a physical connection. Wireless power uses the same fields and waves as wireless communication devices. Various radio-frequency (RF) technologies are used for wireless power transmission.

What are disadvantages of using cascaded transformer?

The main disadvantage of cascading the transformers is that the lower stages of the primaries of the transformers are loaded more as compared with the upper stages. The loading of various windings is indicated by P in Figure.

What are the design challenges of a resonant converter?

In Section VI, resonant converter design challenges and the effects of real life parasitics and parameters are addressed. First, the operational states of a resonant converter are more than a PWM converter. Therefore, synchronous rectifier controller design becomes challenging for a resonant converter.

What are the advantages of resonance transformer?

• Resonant transformer is one of the best choice for high voltage generation which operates on resonance phenomenon (XL= Xc). • In resonance condition, the current through test object is very large and that is limited only by the resistance of the circuit.

What is the resonant tank gain of LLC converter?

The resonant tank gain is function of resonant elements (Lm, Lr and Cr), load and switching frequency. LLC converter design procedure is not direct and finalizing the optimum resonant tank component values will need some iterations. The design steps are summarized below

What is the transient response of a resonant converter?

Second, the transient response of resonant converters is addressed with two different resonant converter control strategies: variable frequency control (VFC) and hybrid hysteresis control (HHC). The key component parasitics and their effects on a resonant converter operation are also discussed in Section VI.
