Measuring currents in multi-phase converters involves performing a current or voltage measurements on pairs of half bridges combined to form current measurement units

摘要

The method involves performing a current or voltage measurements on pairs of half bridges (13) combined to form current measurement units. The current or voltage measurement can be performed in a current measurement unit either on the high side (11) or on the low side (12) of the half-bridge involved. Regulator output parameters are fed to a PWM regulator that generates center-aligned PWM signals.
