set auto_wire_load_selection true #set_wire_load_model "6K_3LM" => sets wire load model on current design to something other than the default one set in .lib file. Usually for larger designs, we set WLM manually, since the default WLM may be smaller designs, and so too optimistic. ...

Moreover, the proposed converter exhibits a continuous input current with zero pulsating at a very low duty cycle. In addition, D2 and D3 operate in zero voltage switching (ZVS), as shown in Fig. 3c, at minimum input voltage and at high load current. The proposed DC DC converter ...
目前,已经有多种DC-DC变换器拓扑被提出,双有源全桥(Dual Active Bridge, DAB)变换器是DC-DC变换器的热门研究拓扑之一,其集成了输入输出端电气隔离、高电压增益、较宽负载范围内实现全体开关器件零电压开通(Zero Voltage Switching, ZVS)等优点[5]。通过控制各个开关桥臂之间的移相,即可实现能量的双向流动。

Quiescent current, also called ground current, is the current used to operate the converter, and is not delivered to the load. IQ is measured when the converter is enabled and the output/load current is zero (0). A small quiescent current is needed to maximize the converter output ...
Power input conditions (single-phase 3-wire):AC90-260V 50-60HZ two-phase (three-wire: zero, fire, ground). Number of channels:8-way universal socket relay controlled and 2-way universal socket output directly. Maximum single-channel power:5000W。
