Electrolytic capacitors immediately after the output of the rectifiers is invalid, as these capacitors will quickly overheat due to the high ripple voltage and will be released from system Ĭ9-C12-DA1-R3-R4-VD4-VD7 and C16-C17-DA2-R9-R11-VD17-VD22 - the compensation voltage (Low Drop) protecting overload and short circuit.

However thanks to the capacitor C8 in the steady state current through the bias power transformer T1 does not flow Ĭ7-C10-C11-L2-VD3-VD5-VD6 and C13 C15.-L2-VD9-VD10-VD16 - output rectifiers with a smoothing LC-filters, made under the scheme Mac Estuary. The capacitance of the capacitors C1, C3 and C2, C4 in the General case are not the same, and the midpoint of the divider offset about half of the supply voltage. Resistors R1 and R2 drain the capacitors C1.C4 when you turn off the source from the network. VD1-VD2-C1, C4-R1-R2 - network rectifier with a capacitive divider. RU1 - varistor, shunt overvoltage pulses coming from the network Ĭ5-C6-L1 - the network filter that suppresses high-frequency oscillations generated by Converter RK1 - the thermistor that limits the starting current to charge the capacitor C1.C4 to safe for diodes VD1 and VD2 value It is executed on a widespread element base and does not contain expensive or scarce components.įU1 - the fuse that protects the power supply line in an accident in the source All these requirements switching power supply (SMPS) submitted in article.
