两象限DC/DC变换器块实现两象限DC/DC功率变换器。您可以选择三种模型类型：开关设备-转换器采用IGBT/二极管对建模，IGBT/二极管对由PWM发生器产生的触发脉冲控制。该模型提供了最精确的仿真结果。开关函数-转换器采用开关函数模型。在交流侧用两个电压源和两个二极管替换开关，在直流侧用两个电流源替换开关。转换器由脉冲宽度调制（PWM）发生器产生的触发脉冲（0/1信号）或在指定周期内平均的触发脉冲（脉冲宽度调制平均：0和1之间的信号）控制。这两种工作模式产生的谐波通常由PWM控制的转换器，也正确模拟整流操作以及消隐时间。这种模型类型非常适合于实时仿真。
The Two-Quadrant DC/DC Converter block implements a two-quadrant DC/DC power converter. You can choose three model types : Switching devices — The converter is modeled with IGBT/diode pairs controlled by firing pulses produced by a PWM generator. This model provides the most accurate simulation results. Switching function — The converter is modeled by a switching-function model. The switches are replaced with two voltage sources and two diodes on the AC side and with two current sources on the DC side. The converter is controlled by firing pulses produced by a PWM generator (0/1 signals) or by firing pulses averaged over a specified period (PWM averaging: signals between 0 and 1). Both modes of operation produce harmonics normally generated by a PWM-controlled converter and also correctly simulate rectifying operation as well as blanking time. This model type is well-suited for real-time simulation.
