Assignee: SANSHA ELECTRIC MANUFACTURING CO., LTD.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A gate drive circuit which drives an output element by amplifying an input pulse signal from a control board comprising:
an N-channel MOSFET and a P-channel MOSFET which are connected in a push-pull to amplify the input pulse signal and whose connection point to each other is connected to the output element, and
a temperature correction circuit which is connected to a gate of the P-channel MOSFET,
wherein
the N-channel MOSFET and the P-channel MOSFET have different thresholds (voltages) at turn-on at low temperatures (V(thL)) and at high temperatures (V(thH)), and
the temperature correction circuit generates a voltage drop which varies as ambient temperature increases, receives the input pulse signal from the control board, and inputs the input pulse signal minus the voltage drop to the gate of the P-channel MOSFET.
