Circuit Schematic SCR DC to DC Converter Circuit using S6008 SCR

Eltronicschool. - This is one of circuit schematic DC to DC converter based on Silicone Controlled Rectifier (SCR). In here SCR used to convert input voltage with other value in output.

In this time, we will give you Circuit Schematic SCR DC to DC Converter Circuit using S6008 SCR like in Figure 1. below.

Description

Circuit schematic like in Figure 1 above is Circuit Schematic SCR DC to DC Converter Circuit using S6008 SCR. According ElectronicKitSchool blog describe that 12V to 1 - 8 Volt, 100mA SCR DC to DC Converter Circuit using S6008 SCR. The main component used in this circuit is SCR served as the DC to DC Converter. 

When SCR1 fires, C2 charges via L1 and rings up to approximately twice the input voltage (24V). At that point, the series resonant circuit attempts to ring back, but is limited by the blocking effect of SCR1 –at this point, SCR1 commutates. Upon the subsequent edge, SCR2 is triggered and discharges C2 into C3 via L1. Since C3 is much larger than C2, the charge contribution of C2 is relatively minor, causing the output voltage to increase only a fraction of a volt. When C2 is discharged to below zero, D3 clamps the voltage to -0.5V and the current through L1 continues to flow until it decays to zero. At this point, SCR2 becomes reverse biased and commutates. Then the process begins again –and runs at several kHZ. This frequency may be controlled either manually (this discussion) or automatically regulated (future discussions).
