Question

The control scheme of an inverter with $V_{dc} = 650\ V$ has estimated that it needs to generate, on average, a voltage of $250\angle20^\circ$ in Phase-B at the inverter terminal. Over a switching cycle, $T_s = 150\ \mu s$, around $\omega t = \pi/2$, determine the switching states and calculate the duty cycles, $d_0, d_1, and\ d_2$, and the associated time intervals, $t_0, t_1, and\ t_2$, for each state.

Name: The control scheme of an inverter with Vdc = 650 V has estimated that it needs to generate, on average, a voltage of 250∠20^∘ in Phase-B at the inverter terminal. Over a switching cycle, Ts = 150 μ s, around ω t = π/2, determine the switching states and calculate the duty cycles, d0, d1, and d2, and the associated time intervals, t0, t1, and t2, for each state.

Step 1

The modulation index is given by the equation: m = Vm/V where Vm is the desired output voltage and V is the DC link voltage. In this case, Vm = 250 and V = 650. Plugging in these values, we get: m = 250/650 = 0.3846 Show more…
