Title:
スイッチモード電源システムおよびこのシステムを備えた可変速駆動装置
Document Type and Number:
Japanese Patent JP4932657
Kind Code:
B2
Abstract:
The system has a secondary winding (Ns) magnetically coupled to a primary inductive assemblies (Np1, Np2) to output direct current output voltage (Us). The assembly is connected in series between a positive input terminal (A2) and two MOSFETs or insulated gate bipolar transistor switches (SW1, SW2). A drain (D2) of the switch (SW2) has a current injection module for injecting current at a mid-point (PMC) of two buffer capacitors (CB1, CB2). One end of a balancing circuit (15) is connected to the mid-point, to balance leakage currents of the capacitors. An independent claim is also included for a speed variator.
