“…Among these, the zero-voltage switching (ZVS) converters can be broadly divided into two categories according to the different bus links in achieving resonance: the resonant DC link system (RDCLS) [1]- [3] and the resonant pole system (RPS) [4]- [10]. The RDCLS uses a resonant circuit composing of resonant inductors paralleled on the DC bus and snubber capacitors paralleled on the power switches, which achieves a periodical zero voltage on the DC bus as a basis for the power switches turning-on.…”

A novel auxiliary resonant commutated pole (ARCP) link for three-phase PWM voltage-fed converter is presented. The ARCP link consists of two auxiliary switches, one resonant inductance, and six diodes, which is simpler than the conventional ARCP designs. Based on the phase and amplitude control, the proposed converter can take a minimum switching times PWM method, which results in reduced losses and a simplified control. In addition, the zero-voltage resonance modes are analyzed. Finally, simulation and experimental results show that the system can realize zero-voltage switching with a unity power factor.

“…The disadvantage of the traditional voltage-source inverter is that the DC/AC conversion mechanism based on PWM modulation, such as abrupt change of voltage waveform which result in the higher requirements of power electronic devices and the load on withstanding voltage mutation and the efficiency of inverter decreased significantly with the reduction of the output power [5] . In addition, the conventional DC / AC converter transfer energy by using hard-switching technology, so the switching loss and the service life of power electronic devices are affected [6] . To reduce the switching loss of power electronic devices and the impact of voltage mutation on switching device and load, a DC/AC converter based on buck regulator is proposed in this paper.…”

The introduction of DC/AC converter based on buck regulator is firstly shown, and the analysis of the converters working principle is taken. The control method applied for DC/AC converter based on buck regulator is studied also. The control effect of the open-loop proportional-differential control and closed-loop proportional-integral control are compared by using PSIM software. The parameters adopted in the realistic simulation, waveforms such as voltage of modulation reference and load were given. The simulation results proved that adopting the DC/AC converter could achieve a good performance and can gain a line frequency as 50Hz and the correctness of theoretical analysis.
