Model 2〔 t1～t2〕 At t1, when the current through S1 is equal to Io/n, the power energy is delivered to the load, the circuit is in half-bridge converterPWMstate. Then the current through S1 maintains to be Io/n. Model 3〔 t2～t3〕 At t2, the auxiliary switch S3 turns on in ...
This Z-source half-bridge converter can solve not only the problems of the shoot-through and limited voltage but also the problem of imbalance at the midpoint voltage of input capacitors. Furthermore, it can generate a broader range of output voltage values and much more kinds of waveforms, ...
These waveforms indicate that there is no switching loss (i.e. zero-voltage switching) at turn-on of the MOSFETs under no-load and full-load conditions. By verifying that the converter has no switching loss under these two operating conditions, we can determine that the converter achieves ZVS...

Figure 1: Basic LLC resonant half-bridge converter The circuit consists of: • A square-wave generator: two power MOSFETs, Q1 (High Side) and Q2 (Low Side), are configured to produce a unipolar square-wave voltage. To prevent any cross- conduction through ...
The half-wave rectifier is a converter which carries out half-wave rectification. In a single-phase context, this is a converter including a diode which may be qualified as P1; in a three-phase context, we use P3, and in a generalized case with n phases, Pn. A single-phase half-wave...
asymmetric half-bridge; flyback converter; constant off-time; resonant converter 1. Introduction The flyback converter is widely used in the low to medium output power range because of the advantages of fewer circuit components and simple control. Compared with the LLC converter, the flyback ...
Different Half-Bridge (HB) converter topologies for an Integrated Voltage Regulator (IVR), which serves as a microprocessor application, were evaluated. The HB circuits were implemented with Stacked Transistors (HBSTs) in a cutting-edge 14 nm CMOS technology node in order to enable the integration...
Full-wave rectifiers use both halves of the AC cycle. This leads to a more efficient conversion of AC to DC compared to half-wave rectifiers. By employing two diodes in a center-tapped configuration or four diodes in a bridge configuration, full-wave rectifiers convert both the positive and ...
