ATX Power Principle, Part 4: standby circuit type 2: In indirect

300Vdc power supply from the circuit bent / primary filter. Effects components: Rhv: limiting resistor, the output voltage follows it to about 270V. R3, R5: Natural (each) for Q3. Q3: standby power, here use Mosfet 2N60. (Dowload full image) R4: Creating negative feedback voltage, using voltage drop on R4 as a sensor to check the current through Q3, through which will be adjusted to Q3 stable operation. ZD1: Voltage Stability foot G, in...

ATX Power Principle, Part 3: standby circuit type 1: In the direct

3.2.Standby circuits using blocking oscillator Type 1: In direct (illustrated by circuit stabdby source LC-200) 300Vdc power supply from the circuit bent / primary filter. Effects components: Q12: blocking oscillator, and standby power. R55/R56: the natural Q12, resistor acts as a "primer" D23: Resetting feedback to maintain oscillation, the output voltage in Anode D28 is negative (-). C19: Filter leveled voltage feedback. R57: Distribution,...

ATX power principle :

1.PRINCIPLES pulse source 1.1. Concept: -Circuit pulse source (also known as source switches on / off switching) is the inverter shall convert the DC power into AC power. 1.2. The diagram inverter: There are basically two types of inverter: serial and parallel. 1.2.1.Diagram inverter serial Pros: Simple, easy to calculate design, easy assembly. Cons: Allows very low tolerance components. Not isolated mass primary and secondary user should...

AC filter circuit, the primary one-dimensional filter adapter

ATX power principle Effects of components: F1: Fuse overcurrent protection, when the phenomenon of slow power line through F1 increase its lead wires will flow, disconnect the power supply to protect the components are not damaged further. TH1: Overvoltage protection fuse, which are composed of one pair of adjacent semiconductor, its maximum voltage of about 230V-270V (depending on source). When the voltage is too high or lightning...
