A solid-state high-voltage direct-current (HVDC) bus voltage controller to provide active power flow control in a hybrid electric aircraft power supply system. The HVDC bus voltage controller includes an active voltage controller and an active rectifier unit configured to control the HVDC bus voltage using the PWM control technique. In one implementation, the active rectifier unit includes high-power and high-frequency semiconductor switches with fast turn-off capabilities. The active voltage controller sends an HVDC bus reference voltage to the active rectifier unit. The low-level controller inside the active rectifier unit is configured to control the HVDC bus voltage to match the HVDC bus reference voltage.
