FAQ

What is Excess work due to thyristor 1 in chopper circuit?
Excess work due to thyristor 1 in chopper circuit is the energy stored in the inductor Lm due to reverse recovery time trr of thyristor T1 of the chopper circuit with di/dt limiting inductors and is represented as WR=0.5*Lm*((Im+(trr*V0)/Lm)-(Im^2)) or Excess energy in chopper circuit=0.5*Reverse di/dt limiting inductance*((Load current of chopper circuit+(Reverse recovery time*Commutation capacitor voltage)/Reverse di/dt limiting inductance)-(Load current of chopper circuit^2)). Reverse di/dt limiting inductance is the inductor connected in series with thyristor 2 of the chopper circuit with di/dt limiting indicators, Load current of chopper circuit is the current flowing across the load of the circuit, Reverse recovery time is the amount of time the current flows in the reverse direction when the forward current simultaneously switches directions due to residual stored charge and Commutation capacitor voltage is the voltage across the capacitor C in the chopper circuit with di/dt limiting inductors.
