Abstract :
An analogue linearising pulsewidth modulator (LPWM) for a three-phase boost inverter is presented. It employs integrators with hold and reset to compute the switching instants. The LPWM enables the output voltages of the boost inverter, which are nonlinear with respect to duty ratio control, to track the control voltages linearly. The theory is verified by experimental data
