6 FAQs about [Rectification and voltage doubling energy storage]

How much space does a synchronous rectifier save?

The latter is a space savings of 53 mm2. Both designs use the same LC filter and a 750-kHz switching frequency. Figure 3 shows the efficiency and power loss of both designs with a 12-V input and a 15-V output. The ideal duty cycle is 20%. The ben-efit of the synchronous rectifier is clear in this example.

What is the difference between Bridge rectification and SDR-Teng?

When the load grows to 10G Ω, which is the level of the matching impedance, the bridge rectification brings a voltage amplitude around 270 V, as shown in Fig. 4 d. The SDR-TENG results in a voltage amplitude to 390 V, which is 44% higher than that of bridge rectification. In addition, the duty ratio increases to 80%.

What happens if load resistance increases to 100G?

When the load resistance increases to 100G Ω, which is much larger than the matching impedance, the voltage amplitude of SDR-TENG reaches 550 V, which is twice of the bridge rectification, as illustrated in Fig. 4 g and h. And the duty ratio is almost 100%, the transferred charge is also more than the bridge rectification.

What is a synchronous rectifier loss?

The rectifier loss is simply the forward voltage drop times output cur-rent per Equation 1. With a synchronous rectifier, there is some dependence on the duty cycle for power dissipation because the conduction losses are caused by the resistance of the FET. This is unlike a diode, where the losses are caused by the forward voltage drop.

Does Bennet's doubler circuit improve power management of Teng?

Liu et al. and Ghaffarinejad et al. [ 25] reported the application of Bennet's doubler circuit in the power management of TENG, which can bring an exponential enhancement during the AC/AC conversion.

What are the advantages of Schottky rectifier synchronous solution?

The Schottky rectifier of load current, the synchronous solution begins to is in a D2PAK package with a typical area of 155 mm2. The improve efficiency. However, the primary benefit of syn-synchronous solution saves 125 mm2 of board space over chronous rectification is that less board space is required.
