How to Convert SMPS into a Solar Charger Circuit Diagram

Image
The post explains a novel way of using an ordinary SMPS unit for charging a battery via a solar panel. The method will result in an extremely efficient and fast solar charging of the connected battery. SMPSs have become very common nowadays and we find them being used in the form of of low voltage DC units wherever needed. The best example is our cell phone chargers which are actually compact SMPS 5V chargers. Solar charger devices are also becoming popular nowadays and folks are constantly in look out for options in the form of solar chargers having the most efficient charging response. Solar panels or PV devices are normally utilized for charging lead acid batteries which tends to take relatively long hour for getting fully charged, and especially when the sunlight conditions are bad things start getting even more sluggish. For tackling the above condition or rather for enabling quicker charging from solar panels, special MPPT based soar chargers have been developed which effecti...

Output Inductor Calculation for SMPS Converters using the Forward Push Pull Half Bridge and Full Bridge Topologies

Image
An output inductor is found at the output of every forward-mode converter. Converters utilizing the forward, push-pull, half-bridge and full-bridge topologies are all forward-mode converters. So, calculation of the output inductance follows the same methodology for all four of these popular topologies. The purpose of the output inductor is to store energy for the load during the time each switching cycle when the power switches (BJTs, MOSFETs or IGBTs) are turned off. The electrical function of the output inductor is to integrate the rectangular switching pulses (pulse width modulated signals with varying duty cycle) into DC. The capacitor following the inductor smooths the DC into clean DC. The design of the output inductor is quite simple. Usually, a self-gapped toroid core is used. Gapped ferrite cores (the ones used for ferrite transformers, eg ETD39) can also be used with no difficulties. The formula for calculating the output inductance is: Vin(max) is the highest peak voltage fo...
