Abstract:
Peak primary current control on the secondary side. In a power converter having a primary side and a secondary side separated by a main transformer, example methods include: driving primary current through a primary winding of the main transformer; creating, on the secondary side of the main transformer, a signal indicative of current through the primary winding of the main transformer; and ceasing the driving of primary current through the primary winding when the signal indicative of primary current reaches a predetermined value.

Claim (Index 15):
A circuit for control of a switching power converter comprising:\n a gate terminal, a winding sense terminal, and output voltage terminal, a primary pulse-width modulation (PWM) terminal, and an external capacitor terminal; a first substrate; a PWM controller defined on the first substrate and electrically cot tried to the output voltage terminal and the primary PWM terminal, the PWM controller configured to create a primary PWM signal driven to the primary PWM terminal; an emulation controller defined on the first substrate, the emulation controller electrically coupled to the winding sense terminal, the output voltage terminal, and the external capacitor terminal, the emulation controller configured to create a signal indicative of primary current by driving current to the external capacitor terminal; and wherein the PWM controller is further coupled to the signal indicative of primary current, and the PWM controller is configured to control duty cycle of the primary PWM signal based on the signal indicative of primary current; wherein the emulation controller further comprises:\n a differential amplifier defining a first differential input, a second differential input, and an amplifier output, the first differential input coupled to the winding sense terminal, the second differential input coupled to the output voltage terminal, and the amplifier output coupled to the external capacitor terminal; and \n an electrically controlled switch coupled between the external capacitor terminal and ground, the electrically controlled switch having a control input coupled to the gate terminal.
