變頻器在許多電氣設備中是必不可少的組件，像配電櫃，控製櫃，一些電氣控製櫃中，都有有變頻器的存在。

Frequency converters are essential components in many electrical equipment, such as distribution cabinets, control cabinets, and some electrical control cabinets.

接下來，跟著高低壓成套電氣設備廠家一起了解一下變頻器的控製電路的組成與(yu) 相關(guan) 特性：

Next, let's follow the manufacturers of high and low voltage complete electrical equipment to understand the composition and related characteristics of the control circuit of the frequency converter:

變頻器控製電路由這些電路組成：頻率、電壓的運算電路、主電路的電壓、電流檢測電路、電動機的速度檢測電路、將運算電路的控製信號進行放大的驅動電路，以及逆變器和電動機的保護電路。

The frequency converter control circuit consists of these circuits: frequency and voltage calculation circuit, voltage and current detection circuit of the main circuit, speed detection circuit of the motor, driving circuit that amplifies the control signal of the calculation circuit, and protection circuit of the inverter and motor.

變頻器驅動電路的HCPL-316J特性：

HCPL-316J characteristics of frequency converter drive circuit:

兼容CMOS/TYL電平；光隔離，故障狀態反饋；開關(guan) 時間500ns；“軟”IGBT關(guan) 斷；欠飽和檢測及欠壓鎖定保護；過流保護功能；寬工作電壓範圍(15～30V)；用戶可配置自動複位、自動關(guan) 閉。 DSP與(yu) 該耦合器結合實現IGBT的驅動，使得IGBT VCE欠飽和檢測結構緊湊，低成本且易於(yu) 實現，同時滿足了寬範圍的與(yu) 調節需要。

Compatible with CMOS/TYL levels; Optical isolation and fault status feedback; The maximum switching time is 500ns; "Soft" IGBT shutdown; Undersaturation detection and undervoltage locking protection; Overcurrent protection function; Wide operating voltage range (15-30V); Users can configure automatic reset and automatic shutdown. The combination of DSP and this coupler realizes the driving of IGBT, making the IGBT VCE undersaturation detection structure compact, low-cost, and easy to implement, while meeting a wide range of safety and regulation needs.
