Description
一种基于 IGBT串联损耗优化电压自适应控制方法 技术领域
本发明涉及电子电力***领域。 具体涉及一种基于 IGBT 串联损耗优化电压自适应 控制方法。
背景技术
20 世纪 80 年代中期出现的半导体电力开关器件——绝缘栅双极型功率管 IGBT (Insulated Gate Biploar Transistor)是一种复合器件, 它的输入控制部分为 M0SFET, 输出级为双极结型晶体管, 兼有 M0SFET和电力晶体管的优点: 高输入阻抗, 电压控制, 驱动功率小, 开关速度快, 工作频率可达 10-40kHz, 饱和压降低, 电压、 电 流容量较大, 安全工作区较宽。 但是 IGBT的缺点在于单个 IGBT的电压、 电流允许值很 难再提高, 为了应用于高电压、 大功率的领域, 通常采用 IGBT串联的方法。
随着电力电子技术在电力***中应用的逐步推广,基于 IGBT串联均压技术的高压阀 正在成为各种新型大功率电力电子装置的核心部件。例如 VSC-HVDC、 STATC0M、 UPFC等。 在这些场合中, 由于串联的 IGBT器件运行的频率较高, 开关速度较快, 很容易在串联 的 IGBT器件中产生电压不平衡的情况, 而高电压、 大功率的应用领域决定了一旦出现 严重的电压不平衡, 串联的 IGBT将不可避免的出现失效甚至损坏。 而串联的 IGBT出现 断路失效后, 反过来又会损坏这些大功率电力电子装置, 造成严重的经济损失。
目前国内外对 IGBT电压平衡化控制分为负载侧控制和栅侧控制两大类。负载侧控制 主要通过在 IGBT集射级两端并联缓冲电路实现串联均压, 但只靠缓冲电路均压时, 体 积及损耗较大, 同时可靠性较差。 因此栅侧控制能为当前 IGBT均压控制的主流方法。 而保证 IGBT串联电压平衡化的同时, 不可避免地导致 IGBT开关损耗的增加, 对于大功 率电力电子装置来说将大大降低其工作效率。
本申请介绍一种基于 IGBT串联损耗优化的电压自适应控制策略, 在保证 IGBT串联 电压平衡化的前提下, 提高 IGBT的开关速度, 降低 IGBT的开关损耗, 为 IGBT串联应 用的实用化指出了一条崭新的技术路径。
发明内容
本发明提出的 IGBT平衡化控制原理是让串联的 IGBT快速跟随参考电压波形, 保证 串联 IGBT的电压平衡性。
本发明提供 一种基于 IGBT 串联损耗优化电压自适应控制方法,所述方法包括以下
步骤:
( 1 ) 检测 IGBT端电压;
( 2) 调整主开关阶段的时间;
( 3) 调整预开关阶段的时间。
所述调整主开关阶段包括调整主开通阶段和调整主关断阶段; 所述调整预开关阶段 包括调整预开通阶段和调整预关断阶段。
所述调整主开关阶段中, 由各自独立的驱动电路控制每个 IGBT; IGBT的驱动电路由 同一个阀基控制单元提供控制信号。
所述步骤 (2) 调整主开关阶段的时间分为下述两个步骤:
( 2-1 ) 通过所述步骤 (1 ) 检测 IGBT端电压, 对 IGBT开关时电压变化率 dv/dt与 阀基控制单元传递来的参考电压电压变化率 dv/dt进行比较, 判断两者之间的差异性, 确定向上级传递降低或提高 dv/dt的信号, 阀基控制单元依据驱动单元传递的信号调整 参考电压 dv/dt;
( 2-2) 通过所述步骤 (1 ) 检测 IGBT端电压, 将 IGBT开关时电压变化率 dv/dt与 阀基控制单元传递来的参考电压电压变化率 dv/dt进行比较,确定降低或提高参考电压 dv/dt, 传递至下级参与 IGBT电压平衡控制电压。
在各驱动单元上进行所述步骤 (3) 调整预开关阶段的时间, 各个 IGBT相互独立, 驱动单元检测 vout电压波形,将检测到的 IGBT实际延迟时间与参考电压给定的预开关 时间进行比较, 确定增加或减少参考电压给定的预开关时间。
所述预开关阶段和主开关阶段调整彼此独立。
参考电压波形如图 1所示, 主要包括预关断阶段 (t0-tl )、 主关断阶段 (tl-t2)、 预开通阶段 (t3-t4) 和主开通阶段 (t4-t5)。 其中预关断阶段和预开通阶段控制原理 相同, 主关断阶段和主开通阶段控制原理相同。
预关断阶段及主关断时间较长时, IGBT的关断损耗将会增加; 而预关断阶段及主关 断时间较短时, IGBT的电压将难以保证平衡性。预开通阶段及主开通时间较长时, IGBT 的开通损耗将会增加; 而预关断阶段及主关断时间较短时, IGBT的电压将难以保证平衡 性。
本专利提出了一种于 IGBT串联损耗优化的电压自适应控制策略, 通过检测 IGBT端 电压, 合理地调整预关断阶段、 主关断阶段、 预开通阶段和主开通阶段时间, 在保证串 联 IGBT电压平衡的前提下提高开关速度, 降低 IGBT开关损耗。
与现有技术相比, 本发明的有益效果在于:
1. IGBT串联时电压平衡可靠度高;
2. IGBT串联时开关损耗低;
3. IGBT开关电压应力可控。

具体实施方式
参考电压波形如图 1所示, 主要包括预关断阶段 (tO-tl )、 主关断阶段 (tl-t2)、 预开通阶段 (t3-t4) 和主开通阶段 (t4-t5)。 其中预关断阶段和预开通阶段控制原理 相同, 主关断阶段和主开通阶段控制原理相同。
主关断阶段(tl-t2)和主开通阶段(t4-t5 )原理框图如图 2所示。 每个 IGBT由各 自独立的驱动电路控制, 阀臂上 IGBT的驱动电路由同一个阀基控制单元提供控制信号。
主关断阶段和主开通阶段优化控制分为调整 1和调整 2两个部分:
调整 1 : 检测 IGBT端电压, 将 IGBT开关时 dv/dt与阀基控制单元传递来参考电压 dv/dt的进行比较。 当两者差异大于允许值时, 向上级传递降低 dv/dt的信号, 当两者 差异小于允许值时, 向上级传递提高 dv/dt的信号。 阀基控制单元检测所有驱动单元传 递来的调整信号, 当所有信号均为提高 dv/dt 时, 阀基控制单元将提高参考电压的 dv/dt; 当有一个信号为降低 dv/dt时, 阀基控制单元将降低参考电压的 dv/dt, 调整后 的参考电压将传递给各个驱动单元。
调整 2: 检测 IGBT端电压, 将 IGBT开关时 dv/dt与阀基控制单元传递来的参考电 压 dv/dt进行比较。 当 IGBT开关时 dv/dt大于阀基控制单元传递来参考电压的 dv/dt, 将降低参考电压的 dv/dt; 当 IGBT开关时 dv/dt小于阀基控制单元传递来参考电压的
dv/dt, 将提高参考电压的 dv/dt。 调整后的参考电压传递至下级参与 IGBT电压平衡控 制。
预关断阶段 (tO-tl ) 和预开通阶段 (t3-t4) 控制原理框图如图 3所示。 此部分在 个驱动单元上实现, 各个 IGBT相互独立。 在各个驱动单元上检测 vout电压波形, 判断 IGBT所需延迟时间。 将检测到的 IGBT实际延迟时间与参考电压给定的预开关时间进行 比较, 当检测到的 IGBT实际延迟时间大于参考电压给定的预开关时间时, 增加参考电 压给定的预开关时间; 当检测到的 IGBT实际延迟时间小于参考电压给定的预开关时间 时, 减短参考电压给定的预开关时间。
本发明提出的基于损耗优化的电压自适应 控制策略分别优化预开关阶段和主开关 阶段, 保证 IGBT电压平衡的前提下, 降低 IGBT开关损耗, 其中预开关阶段调整与主开 关阶段调整相互独立。
依据上述控制原理, 仿真结果如下图所示:
图 4、 图 5为参考电压波形关断阶段调整前后波形对照;
图 6、 图 7为 IGBT关断波形调整前后对照。 从图中可知预关断时间及主关断时间经 优化后, IGBT关断速度明显增快, IGBT关断损耗降到较理想值。
图 8、 图 9为参考电压波形开通阶段调整前后波形对照;
图 10、 图 11为 IGBT开通波形调整前后对照。 从图中可知预开通时间及主开通时间 经优化后, IGBT开通速度明显增快, IGBT开通损耗降到较理想值。
以上具体实施方式仅用以说明本发明的技术方案而非对其限制, 尽管本领域的技术 人员阅读本申请后,参照上述实施例对本发明进行种种修改或变更,但这些修改和变更, 均在申请待批本发明的权利申请要求保护范围之内。
