Title:
【発明の名称】ビデオ表示装置用電源
Document Type and Number:
Japanese Patent JP2608880
Kind Code:
B2
Abstract:
A regulating power supply for a video display apparatus includes a switching transistor that periodically energizes a transformer winding. Input switching pulses for the transistor are varied in width and frequency to optimize power transfer via the transformer. The charge and discharge rates of a capacitor determine the pulse width and frequency. The capacitor charging current is selectively switched to be connected to the capacitor while the capacitor discharge current is controlled in response to a feedback signal derived from the regulated voltage level.
