The control circuit of the converter separates the loop control circuit and the closed loop co®ntrol circuit according to the control mode. The former is mainly used in some special equipmδent with low requirements; the latter has the function of automatic control and≈ adjustment, and is widely used in various working λmachines.
According to the nature of the control signal, it is divided into analog control circuit and digitβal control circuit. Analog signal is the most commonly used DC v→oltage and current, easy to use the method of electricity to be processed and transfo∞rmed; digital signal is a set of information parameters wit✔h discrete values of the discontinuous change of the signal. ¶Digital control has high precision, but the circuit is m"ore complex and expensive. Therefore, digital-analog hybrid control circuεits are widely used in practice. In addition, the control circuit using the microco$mputer also has many advantages.
