An electric power system (EPS) may comprise a first power conversion channel and a second power conversion channel connected in parallel with a permanent magnet synchronous machine (PMSM). The first power conversion channel may be suitable for a load having a first electronic characteristic. The second power conversion channel may be suitable for a load having a second electronic characteristic. The first power conversion channel may comprise a first rectifier configured to receive an alternating current (AC) power from the PMSM and rectify the AC power into a first direct current (DC) power, a first buck converter configured to receive the first DC power from the first rectifier and reduce a voltage of the first DC power, and a first output filter configured to filter the first DC power and supply the first DC power to a first load.
