Embodiment Construction
[0034] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0035] like figure 2 Shown is an anti-noise high-voltage gate drive circuit proposed by the present invention, including a high-voltage level shift module 1, a common-mode noise elimination composed of a first common-mode noise elimination module CMR1 and a second common-mode noise elimination module CMR2 Circuit 2, SR latch 3 and drive module 4. The high-voltage grid drive circuit proposed by the present invention mainly uses narrow pulses to reduce the power consumption of the circuit. The high-voltage level shift module 1 includes two input terminals and three output terminals, which are used to transfer the input two-way low-voltage pulse control signals Converted into a high-voltage pulse signal, together with the output of the high-voltage common-mode signal, the signal level is improved through the LDMOS tub...
