DR-100-24 Current Sensing Function Chip

The purpose of DR-100-24 series connection is to increase the working voltage, the requirements are higher than parallel connection, mainly static voltage equalisation and dynamic voltage equalisation, especially dynamic voltage equalisation is difficult. Chengdu Jialing company proposed capacitive motherboard technology (1 + N) only series dynamic voltage clamping voltage equalisation has been in the industrial experimental stage. If the dynamic voltage is not good, to cause the series arm of each device on the Vce voltage is not equal, resulting in an over-voltage affects the same arm of a series of electrical breakdown.

DR-100-24 series-parallel connection should be avoided as far as possible, do not take low voltage and small current devices, through series-parallel connection attempt to solve the high voltage and high current, this practice is often the opposite of what it should be, and the device increases the reliability of the worse, the circuit is also complicated, etc., in the conditions that must be done, be careful. Today’s single IGBT voltage or current can basically meet the needs of users, with the development of the times circuit improvements, there will be a higher voltage, higher current power devices, it is inevitable.

DR-100-24 can be used for inverter. It is an advanced hybrid integrated power devices, IGBT, drive circuit, protection circuit integration, so with high speed, high efficiency, low power consumption, and optimised gate drive and protection circuit, undervoltage locking, with current sensing function chip, overcurrent and short circuit protection, more superior, the overall reliability is greatly improved. ipm has four kinds of circuit form: single-tube package (h), double-tube package (d), six in one package (C), and seven-in-one package (R). Due to the IPM pass-state loss and switching loss are relatively low, can make the heat sink is reduced, so the size of the whole machine can also be reduced, and self-protection capabilities, reducing the development and use of overload damage in the case of the chance.
