Title:
OPERATION METHOD OF POWER TRANSISTOR CIRCUIT
Document Type and Number:
Japanese Patent JP2023160795
Kind Code:
A
Abstract:
To provide a method.SOLUTION: A method includes switching off a power transistor circuit (1) within an electronic circuit. The electronic circuit includes a power source (2), a load circuit (3), and a power transistor circuit (1) connected between the power source (2) and the load circuit (3). The step of switching off the power transistor circuit (1) includes a step of operating at least one power transistor (10;101, 10n) included in the power transistor circuit (1) in an avalanche mode, and as a result, at least a portion of the energy stored in the electronic circuit before the step of switching off the power transistor circuit (1) is dissipated in the at least one power transistor.SELECTED DRAWING: Figure 1
