Impact of PPAM for Power Modulation in Solar & Battery Bi-directional DC-DC Converter

Abstract

In this paper, the power modulation is controlled with the phase angle PWM signals in isolated bi-directional DC-DC (IBDC) converter integrated with the PV & storage system. The electronics switch of IBDC satisfies the load demand and manages the power flow to system. The PWM phase angle control mechanism (PPAM) manages the power flow between solar and battery by PWM with phase angle of low voltage (LV) and high voltage (HV) of IBDC. The High-power transfer is taken turn ratio of transformer between the battery and the DC link is controlled by IBDC. The PPAM has been performed over wide variations in phase angle, voltage and load variation. The simulation result reveals the efficiency and the power flow control.
