Operation principle of a voltage converter. Circuitry A converter of direct current into alternating current or a DC/AC converter is today a popular attribute of many automobilists. This unique device will help to connect the required appliance in the AC main in the car without the domestic network. A simple concept will enable you to understand how a converter works. The master oscillator is assembled on VT1 transistor and R3, R4, R5, C3 chain. DD1.2 flip-flop divides pulse frequency in half. Pulses at 50Hz frequency are formed at the outputs. They manage VT2, VT3 keys, working on the push-pull power amplifier circuit. A transformer serves as a load here. It increases the pulse voltage up to 220V. Power voltage is supplied to the output stage transistor collectors via halves of the primary transformer winding, to the master oscillator and DD1 flip-flop - via R1, VD1parametric stabilizer. Stabilizer and C1 capacitor together eliminate the effect of key transistors on the operation of other circuit elements. C4 and C5 capacitors accelerate switching of transistor keys, facilitating their operation. DD1.1 flip-flop has D input connected to the positive power output through R2, while C input is connected to the master oscillator output. The flip-flop is designed to monitor battery status and reports of its discharge to the level set by R2 resistor. The operation principle here is as follows. With a maximum battery charge the voltage at D input D of DD1.1 flip-flop is above ...
