Title:
PARALLEL DRIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/221292
Kind Code:
A1
Abstract:
A parallel drive circuit (50) has a first semiconductor switch element (1) and a second semiconductor switch element (2). A first drain terminal (1b) of the first semiconductor switch element (1) is connected in parallel to a second drain terminal (2b) of the second semiconductor switch element (2), and a first source terminal (1c) of the first semiconductor switch element (1) is connected in parallel to a second source terminal (2c) of the second semiconductor switch element (2). A first on-resistance, i.e., a resistance of the first semiconductor switch element (1) in the on-state, increases when the temperature of the first semiconductor switch element (1) increases, and a second on-resistance, i.e., a resistance of the second semiconductor switch element (2) in the on-state, increases when the temperature of the second semiconductor switch element (2) increases.
