What is LLC topology? An LLC power stage is sown in Figure 2.1. The circuit has two full bridge circuits separated by an isolation transformer. The transformer ratio is set for nominal operating voltage. The resonant tank gain is function of resonant elements (Lm, Lr and Cr), load and switching frequency.

What is series resonant inverter? Resonant inverters are electrical inverters based on resonant current oscillation. In series resonant inverters the resonating components and switching device are placed in series with the load to form an underdamped circuit. If the switching element is a thyristor, it is said to be self-commutated. Read more on en.wikipedia.org An … Read more

How does dual active bridge work? A dual active bridge is a bidirectional DC-DC converter with identical primary and secondary side full-bridges, a high frequency transformer, an energy transfer inductor and DC-link capacitors. The control directs power between the two DC buses such that the leading bridge delivers power to the lagging bridge. Read more … Read more

What is parallel resonant inverter? Parallel resonant inverter is the dual of a series resonant inverter. It is supplied a current source so that circuit offers a high impedance to the switching current. A parallel resonant circuit current is continuously controlled inverter. Read more on www.ijareeie.com An electrical circuit called a parallel resonant inverter is … Read more

What is the advantage of flyback converter? Advantages of flyback converter. The primary is isolated from the output. Capable of supplying multiple output voltages, all isolated from the primary. Ability to regulate the multiple output voltages with a single control. The Flyback converters use very few components compared to the other types of SMPSs. Read … Read more
