In this Thesis an overview on the state of the art of direct drive architecture for Hall
Effect Thrusters (D2HET) is given.
Direct and indirect advantages are examined in relation with different kinds of missions,
and two parameters, related to thruster duty cycle and thruster power fraction, are de-
fined in order to assess a qualitative estimate.
As an experimental campaign is to be conducted on a 5 kW Hall Thruster in high thrust
and high I sp regimes, a setup for the experiment is proposed and the D2HET system
has been simulated in first approximation to assess its behaviour.
A photovoltaic plant has been designed in accordance with the experiment requirements,
and a code has been developed to define the final architecture.
The simulation has been functional to the definition of the critical components used in
the filter.
