1.軟啟動充電電阻應用范圍：
高壓大容量儲能電容充電保護熱敏電阻是華巨電子專門應用于充儲能電容充電保護用熱敏電阻，儲能電容初始充電電流進行限制，防止上電開機因儲能電容充電電流過大引起設備損壞,防止大浪涌電流對設備的破壞。
高壓大容量儲能電容大量地應用于工業產品中，由于電容兩端電壓不能躍變的特性，在系統開機的瞬間，電網能量往電容的灌電流往往達到上百安培的峰值水平，如此高的開機電流嚴重威脅電路中的整流器件與過流保險絲，同時也會給公共商業電網帶來很大的諧波污染。因此幾乎所有電路中都設置了“開機浪涌抑制電路”，將開機沖擊電流抑制到合理的水平。
傳統的“浪涌抑制元件”是常見的固定阻值“水泥電阻”，尤其是在千瓦以上功率的產品中，普遍使用大功率“水泥電阻”作為浪涌抑制元件。從開機浪涌抑制電路設計的初衷來看，固定電阻可以滿足設計的基本功能—抑制開機充電電流。
但是固定電阻本身又帶來了新的安全隱患—由于與“浪涌抑制元件”并聯的繼電器存在不能有效閉合的可能性，如機械疲勞，驅動故障，負載故障等情況下，持續的負載電流流過這個阻值較高的固定電阻（常用阻值在10~100歐姆），勢必會產生極高的溫度，
導致“水泥電阻”冒煙，炸裂等不安全現象，極端情況下PCB會被高溫熔毀甚至點燃。這是線性電阻在浪涌抑制應用中存在的缺陷要解決這個問題，華巨電子推出具有浪涌抑制功能的正溫度系數陶瓷熱敏電阻PTC。其獨特的正溫度系數特性（即阻值隨溫度增加而加大）能有效抑制器件本身溫度的持續增加，其溫度變化過程如下:
PTC低溫低阻=〉被電流加熱=〉溫度增加=〉（當超過PTC動作溫度后）阻值增大=〉電流減小=〉熱功率減小=〉PTC阻值繼續增大（直到幾十KΩ）=〉發熱與散熱平衡=〉PTC溫度維持在動作點附近（約130~150°C）。
從以上分析可以看出，華巨電子的浪涌抑制PTC的“阻值-溫度”正相關特性使它具有“自保護”的功能—在繼電器不能閉合的故障情況下，負載電流產生的熱功率只能將它加熱到居里溫度點附近，有效地避免了類似“水泥電阻”溫度失控的現象，意味著它可以安全地保護自身，同時保護位于其后方的下游電路，而且在繼電器故障排除后，它本身還可以自動恢復原有的功能。
因此，華巨的浪涌抑制PTC為提高開關電源的安全性與可靠性提供了幫助，是理想的開機浪涌電流抑制元件，這款產品正逐步廣泛地為空調、工業變頻器、電源等行業提供安全可靠的開機浪涌保護。該PTC熱敏電阻主要用于數字化焊機 、逆變直流手弧焊機、逆變直流氬弧/手弧焊機等焊接設備的過熱、過流保護。其主要原理為當焊接設備正常工作時流經PTC熱敏電阻的電流不超過其最大工作電流，PTC處于低阻狀態，當出現異常狀態時電路電流大大超過額定電流時，PTC陡然發熱，阻值驟增至高阻態，從而限制或阻斷電流，保護電路不受損壞。電流電流回復正常后，PTC亦自動回復至低阻態，電路恢復正常工作。
大功率電子設備的輸入電路大都采用電容濾波型整流電路，在進線電源合閘瞬間，由于電容器上的初始電壓為零，電容器充電瞬間會形成很大的浪涌電流，特別是大功率大功率電子設備，采用容量較大的濾波電容器，使浪涌電流達100A以上。在電源接通瞬間如此大的浪涌電流，重者往往會導致輸入熔斷器燒斷或合閘開關的觸點燒壞，整流橋過流損壞；輕者也會使空氣開關合不上閘。上述現象均會造成大功率電子設備無法正常工作，為此幾乎所有的大功率電子設備都設置了防止流涌電流的軟啟動電路，以保證電源正常而可
靠運行。下圖（1）是采用繼電器K1和限流電阻WMZ13A系列耐沖擊PTC熱敏電阻
構成的防浪涌電流電路。電源接通瞬間，輸入電壓經整流（D1～D4）和限流電阻RT對濾波電容器C1充電，防止接通瞬間的浪涌電流，同時輔助電源Vcc經電阻R2對并接于繼電器K1線包的電容器C2充電，當C2上的電壓達到繼電器K1的動作電壓時，K1動作，其觸點K1.1閉合而旁路限流電阻R1，電源進入正常運行狀態。限流的延遲時間取決于時間常數（R2C2），通常選取為0.3～0.5s。為了提高延遲時間的準確性及防止繼電器動作抖動振蕩，延遲電路可采
用圖2所示電路替代RC延遲電路。

應用和選型
l 典型應用電路:
Ⅱ選型
根據下列公式來選擇充電電容
C
: 濾波電容.
Tc: PTC的居里溫度Ta :環境溫度
V : 電容器兩端最高充電電壓,電源電壓為交流電，V是交流電的峰值。
K 系數
直流DC時 K = 1, 三相交流電整流時 K = 0.96, 半波整流時 K =
0.76
當單個PTC浪涌抑制熱敏電阻不能滿足要求時，可以多只并聯使用
PTC軟啟動電阻最大負載電容量與電容充滿電電容兩端的電壓平方成反比。所以相同環境條件下電壓降一半最大負載電容量可以增大4倍。
