Dynamic Response Simulation of Half-Bridge Converter - 15/11/2025 15:38 EST
Budget: $10 – $30 USD
By using Matlab I need to solve it Dynamic Response of Half-Bridge Converter
Consider the half-bridge converter of Figure 2.1. The system parameters are
L = 690 uH, R = 5 ms, VDc/2 = 600 V, Vs = 400 V, m = 0.68, and fs =
1620 Hz (or equivalently Ts = 617 Ms). Initially, the converter is in a steady
state. Then, m is changed from 0.68 to 0.685, Vs is changed from 400 to 415 V,
and VDc/2 is changed from 600 to 605 V, respectively, at t = 0.2 s, t = 0.7 s,
and t = 1.5 s.
Assignment: Perform the simulation using both the switched model and the average model and plot the results on the same figure for: (Due date: Oct. 25 2025)
1. Terminal voltage V
2. DC current i,
3. DC power Poc
4. Output currenti
Then there are another plot but related to the first ,
Closed-Loop Response of the Half-Bridge Converter
Consider the half-bridge converter of Figure 3.1 with parameters L = 690 H,
R = 5 ms, Ton = 0.88 ms, Va = 1.0 V, VDc/2 = 600 V, Vs = 400 V, and
fs = 1620 Hz. To achieve a closed-loop time constant of 5 ms, the compensator
parameters are chosen as kp = 0.138 S2 and kj = 1.176 S/s.
Initially, the half-bridge converter system is in a steady state and i = 0. The
current command, iref, is first changed from 0 to 1000 A, at t = 0.1 s, and then
changed from 1000 to - 1000 A, at t = 0.2 s. These correspond to changes in
the AC-side power from 0 to 400 kW and from 400 to -400 kW, respectively.
