Photovoltaic Systems for Electrolysis Using a Maximum Power Point Tracker
2006 IEEE 24th Convention of Electrical & Electronics Engineers in Israel, 2006Electrolysis is the process of decomposition of a substance into its chemical components by an electric current. The process takes place in a solution by an electrolytic cell usually at low voltage and high current. A circuit with a voltage source and an internal resistance may represent the characteristic of the electrolytic cell.

A robust maximum power point tracker with fully analog implementation
2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC), 2017An analog circuit for maximum power point tracking of a PV battery charger with minimum number of elements is proposed which works in a full range condition with a fixed switching frequency. In conventional MPPT algorithms which provide PV current or voltage reference value as output, fast climate changes may cause system instability.

Direct-sequence maximum power-point tracker for photovoltaic sources
2010 Power and Energy Conference At Illinois (PECI), 2010A digital gradient-ascent algorithm is presented to identify and maintain the peak power operating point of a photovoltaic (PV) source with variable I–V characteristics. The approach employs a low-level dither, realized by a one-bit, 64-sample pseudorandom noise (PN) sequence, to perturb the duty cycle of a boost converter that extracts energy from a ...
