IPC: H02M3/155
Filed: 1990-11-30
Abstract: PURPOSE:To provide sufficiently small current standard for a coil, a rectifier, etc., to reduce in size, and further to reduce noise by providing a system for producing a DC output through a rectifier when a main switch is closed. CONSTITUTION:When a main switch Q1 is closed by a signal VB1 at a time t1, the voltage VL1 between both ends of a coil L1 becomes a voltage of a DC power source Eb, and a DC output is sent to a filter F through a rectifier DD. A current IL1 flowing in the coil L1 linearly increases. In this case, a control circuit 2 closes a control switch Q2 by a signal VB2, but since a reverse voltage is applied to a diode D2, no current flows. When the circuit 2 opens the switch Q1 by a signal VB1 at a time t2, the current flowing to the switch Q1 is transferred to a resonance capacitor C1. Then, the voltage VC1 between both ends of the capacitor C1 is raised according to the resonance characteristic of the coil L1 and the capacitor C1, while the voltage VL1 between both ends of the coil L1 is reduced.
