The control circuit of the converter separates the loop control circuit and the closed loop control circuit according to the control mode. The former is mainly used in some special equipment with low requirements; the latter has the function of automatic control and adjustment, and is widely used in various working machines.
According to the nature of the control signal, it is divided into analog control circuit and digital control circuit. Analog signal is the most commonly used DC voltage and current, easy to use the method of electricity to be processed and transformed; digital signal is a set of information parameters 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, the control circuit using the microcomputer also has many advantages.
