Embodiment Construction
[0008] Below in conjunction with the accompanying drawings, the embodiments of the present invention are described in detail: the present embodiment is implemented on the premise of the technical solution of the present invention, and provides detailed embodiments and specific descriptions, but the protection scope of the present invention is not limited to the following example.
[0009] refer to figure 1 The anti-gate drive signal oscillation circuit involved in this embodiment includes: a drive chip IC, a small gate resistor R1 in series, a high-end switch tube T1, a low-end switch tube T2, a gate-source parallel resistor R2, and a bidirectional Zener diode. D1, current limiting resistor R3, fast recovery diode D2, diode D3, diode D4, diode D5, diode D6, capacitor C. The output signal of the driver chip IC reaches the gate of the high-end switch tube T1 through the gate series small resistor R1, the low-end switch tube T2, the gate-source parallel resistor R2 and the bidir...
