Control method and system for compensating for the dead-times in PWM control

摘要

The method involves integrating output voltage (V-ph) during determined time window with down time using an analog integrator by an electronic device (100) to determine compensation duration using an instant detected during charge/discharge of a capacitor of the integrator. The compensation duration is applied to a switching arm connected between power supply lines to correct width of current impulsion or following impulsion. An independent claim is also included for a system for compensating down-time in a pulse-duration modulation type command applied to a switching arm.
