Title:
STEP-UP CHOPPER CIRCUIT
Document Type and Number:
Japanese Patent JPH08266038
Kind Code:
A
Abstract:
PURPOSE: To materialize a step-up chopper circuit where a low withstand voltage switching element can be applied.
CONSTITUTION: This step-up chopper circuit is composed of a reactor 1 fitted with a middle tap, which is connected in series to the plus side of an input DC power source, a switching element 2, whose collector is connected to this middle tap and whose emitter terminal is connected to the minus side of the input DC power source, a diode 3, which is connected in series between the output side of the reactor 1 fitted with a middle tap and the plus side of a DC output circuit, and a capacitor 4 which is connected in parallel to the DC output circuit, on the output side of the diode 3.
