Trouble-free Power Supply provides output power 220 W (current 1A). In 12/220 mode of switch SB1 the voltage of accumulator is attached to the multivibrator Q3 Q4, frequency of which is 50 Hz. Multivibrator is sloped by the powerful switches Q1, Q6. Then voltage increases and given on the transformer T1. Voltage (220 V, frequency 50 Hz) through the filters C2 L1 C1 act to the loading from the secondary winding of transformer T1. When the switch SB1 turns on the position 220/12 a master oscillator disconnected, the voltage from the socket ХР1 through the filter C2 L1 C1 act on the winding I of transformer T1 and through the diodes D2, D3 charges an accumulator by a current of 6А.
