Regulating output currents and/or voltage of switched mode power supply involves using reference value formed internally to influence voltage regulator in switched-mode power supply

摘要

The method involves using a reference value formed internally within the circuit for influencing a voltage regulator (3) in the switched-mode power supply, which also contains a transformer (2). The method involves setting a constant duty cycle for the secondary current. The electronic switch for the primary current is driven by the voltage regulator via a series resistance with a shortened output signal. Independent claims are also included for the following: a circuit for implementing the method.
