功率电容器
功率转换电路的直流链路部分在转换器的输入和输出部分之间提供直流电压。所有类型的功率转换都需要直流链路级,它将输入与输出 "连接 "起来。直流链路为转换器/逆变器部分提供存储能量,还能对转换器/逆变器产生的开关瞬态进行滤波。
Power Electrolytic and Film Capacitors are used in this DC link section. Film capacitors have higher voltage ratings (>600VDC) and ripple current capabilities, but lower bulk capacitance. Electrolytic capacitors have more bulk capacitance, but lower voltage (<550VDC) and ripple current. Each type has benefits and drawbacks and the specific type used is usually determined by which characteristics are best for a particular design.
