TC787 chip introduction and internal structure diagram

Memory chip

TC787AP is a monolithic integrated circuit designed and manufactured by advanced IC technology. It can work with single power supply or dual power supply. It is mainly suitable for three-phase thyristor phase shift trigger circuit and three-phase triode pulse width modulation circuit to form a variety of Voltage regulation and converter devices. As a replacement product of TCA785, this circuit has the advantages of low power consumption, strong function, high input impedance, good anti-interference performance, wide phase shift range and few external components, compared with the popular KC series circuits in the domestic market; Easy to install and reliable. Only one such integrated circuit is needed to complete the three-phase phase shifting function of three TCA785 or five KC series device combinations (three KC009 or KC004, one KC041, one KC042). Therefore, TC787, TC788 can be widely used in three-phase full control, three-phase half-control, three-phase zero-crossing and other power electronics, electromechanical miniaturized product phase shift trigger system, thus replacing TCA785, KC009, KC004, KC042, KC042 and other similar circuits In order to improve the life of the whole machine, reduce the volume and reduce the cost, it provides a new and more effective way.
