6 晶閘管保護
晶閘管承受過電壓、過電流的能力很差，這是它的主要缺點。晶閘管的熱容量很小，一旦發生過電流時，溫度急劇上升，可能將pn結燒壞，造成元件內部短路或開路。例如一只100a的晶閘管過電流為400a時，僅允許持續0.02s，否則將因過熱而損壞；晶閘管耐受過電壓的能力極差，電壓超過其反向擊穿電壓時，即使時間極短，也容易損壞。若正向電壓超過轉折電壓時，則晶閘管誤導通，導通後的電流較大，使器件受損。
6.1 晶閘管的過壓保護
在晶閘管兩端並聯r-c阻容吸收回路，如圖3所示，利用電容吸收過壓。其實質就是將造成過電壓的能量變成電場能量儲存到電容中，然後釋放到電阻中消耗掉。
晶閘管從導通到阻斷時，和開關電路一樣，因線路電感（主要是變壓器漏感lb）釋放能量會產生過電壓。由於晶閘管在導通期間，載流子充滿元件內部，所以元件在關斷過程中，正向電壓下降到零時，內部仍殘存著載流子。這些積蓄的載流子在反向電壓作用下瞬時出現較大的反向電流，使積蓄載流子迅速消失，這時反向電流消失的極快，即di/dt。因此即使和元件串連的線路電感l很小，電感產生的感應電勢l（di/dt）值仍很大，這個電勢與電源電壓串聯，反向加在已恢復阻斷的元件上，可能導致晶閘管的反向擊穿。這種由於晶閘管關斷引起的過電壓，稱為關斷過電壓，其數值可達工作電壓峰值的5∼6倍，所以採取抑制措施。
阻容吸收電路中電容器把過電壓的電磁能量變成靜電能量存貯，電阻防止電容與電感產生諧振、限制晶閘管開通損耗與電流上升率。這種吸收回路能抑制晶閘管由導通到截止時產生的過電壓，有效避免晶閘管被擊穿。
阻容吸收電路安裝位置要盡量靠近模塊主端子，即引線要短。好採用無感電阻，以取得較好的保護效果。
6.2 晶閘管的過流保護
由於半導體器件體積小、熱容量小，特別像晶閘管這類高電壓大電流的功率器件，結溫受到嚴格的控制，否則將遭至損壞。當晶閘管中流過大於額定值的電流時，熱量來不及散發，使得結溫迅速升高，終將導致結層被燒壞。
產生過電流的原因是多種多樣的，例如，變流裝置本身晶閘管損壞，觸發電路發生故障，控制係統發生故障等，以及交流電源電壓過高、過低或缺相，負載過載或短路，相鄰設備故障影響等。
晶閘管過電流保護方法常用的是快速熔斷器。由於普通熔斷器的熔斷特性動作太慢，在熔斷器尚未熔斷之前晶閘管已被燒壞；所以不能用來保護晶閘管。快速熔斷器由銀制熔絲埋於石英沙內，熔斷時間極短，可以用來保護晶閘管。
與普通熔斷器比較，快速熔斷器是專門用來保護半導體功率器件過電流的。它具有快速熔斷的特性，在流過6倍額定電流時其熔斷時間小於50hz交流電的一個周期（20ms）。一般說來快速熔斷器額定電流有效值應小於被保護晶閘管的額定有效值，同時要大於流過晶閘管的實際有效值。
