| 摘 要： | 三电平脉冲宽度调制(PWM)逆变器正被广泛使用,采用数字控制能提高逆变器的性能.采用移相控制方式使三电平逆变器的开关管工作在零电压零电流开关的条件下,每个主开关管承受的电压应力为输入电压的一半,飞跨电容型电压源逆变器拓扑较其它的多电平拓扑(如级联型逆变器、中点钳位型逆变器)有许多独特的性质.建立了以TMS320LF2407A型数字信号处理器(DSP)控制芯片设计的移相脉冲宽度调制方式,控制飞跨电容型三电平逆变弧焊电源.

| Abstract: | Three-level (TL) Pulse-Width-Modulate (PWM) converters has a number of applications and digital control enhances their performance. A Zero Voltage and Zero Current Switch (ZVZCS) TL DC-DC converter was proposed by using phase-shift control with the flying capacitor in the primary side to achieve ZVS for the outer switches. The voltage value of the switches of the three-level leg is the half of the input voltage. Compared with other three-level topologies, the Flying Capacitor Voltage-Source Converter (FC-VSC) topology has a number of unique characteristics such as the Cascaded Converter and the Neutral-Point-Clamped one.A PWM controller suitable for three-level flying capacitor converters was designed by using a popular TMS320LF2407A DSP board for implementation. |
