The control circuit of the converter separates the loop control circuit and the closed lo→op control circuit according to the control mode. The former is mainly used in some special≤ equipment with low requirements; the latter has the functi↓on of automatic control and adjustment, and is widely used in various workingλ machines.
According to the nature of the control signal, it is divided into analog control circ∏uit and digital control circuit. Analog signal is the most com↔monly used DC voltage and current, easy to use the method of electricity to be processed and transformed; digital signal is a set of information pβarameters with discrete values of the discontinuous change of the signal. Digital control has≠ high precision, but the circuit is more complex and expensive. Therefore,÷ digital-analog hybrid control circuits are widely used in practice. In addition, th∞e control circuit using the microcomputer also has many advantages.
