What is the topology of HFAC inverter bridge arm?
Abstract: A new topology of the high frequency alternating current (HFAC) inverter bridge arm is proposed which comprises a coupled inductor, a switching device and an active clamp circuit. Based on it, new single-phase and three- phase inverters are proposed and their operating states are analysed along with the traditional H-bridge inverter.
How can a traditional H-bridge inverter arm be modified?
The traditional H-bridge inverter arm can generate outputs of 0 and ±Vin between the central node, as in Fig. 2a. It can be modi ed by fi replacing the upper switches with coupled inductors, as shown in Fig. 2b.
What is a HFAC inverter?
One critical component of HFAC systems is their front-end inverter, which converts DC to HFAC. A common topology for single-phase systems is the H-bridge [see Fig. 1a], which is also refers to as the full bridge or the buck inverter .
How effective is a coupled inductor bridge arm?
A coupled inductor bridge arm is integrated in them to achieve soft switching, electrical isolation, and structural exibility. Their effectiveness is validated by fl experimental tests on a 400-W prototype. The traditional H-bridge inverter arm can generate outputs of 0 and ±Vin between the central node, as in Fig. 2a.
How much inductance should a HF transformer have?
inductance for the HF transformer should be between 0.2 and 0.7 mH. Clearly, as the leakage inductance of the HF transformer increases, the total switching loss decreases due to an increase in the range of ZVS, while the
