This is a power supply circuit that produce voltage 12 to 24 V. It is very simple, doesn’t need regulator just bridge rectifier, filter capacitor and transformer. A bridge rectifier makes use of four diodes in a bridge arrangement to achieve full-wave rectification. This circuit will give you 15 VDC at up to 3A. …
Read MoreWARNING: Don’t touch any part of the circuit when the circuit is running (connected to the powerline), this circuit is not isolated from mains supply. This is transformerless power supply circuit. This circuit is used to generate fixed voltage power supply capable of supplying 35mA. This circuit uses 4 diodes in a bridge that …
Read MoreThis low noise audio power supply circuit can reduces noise and ripple voltage by 40dB over the 100Hz to 20kHz audio range. In portable application such as cellular phones and multimedia notebook computers, a clean source of 5V power for driving audio circuits can be provided by this circuit. Noise up to 1000Hz or so …
Read MoreThis is example of a simple inverter that can be used to power fluorescent lamp and a small strobe. This circuit will produce over 400VDC from a 12 VDC, 2.5 A power supply or marine battery or an auto. This circuit is very simple because it does not require custom transformers or coils. Also all …
Read MoreThis is a circuit that produces constant current constant voltage SMPS. To efficiently charge a battery, we can use constant current constant voltage SMPS. This circuit produces 600 mA at constant current mode and 7.2V at constant voltage mode. Here is the circuit: The operation of this circuit is simple, When the …
Read MoreDesigning wide range variable power supply using linear regulator is easy, but suffer terrible efficiency when it should regulate 60 Volt constant source down to 5 Volt or lower, the efficiency would be 5/60 or 8.33% at maximum effort, really bad. Using switching technology, the efficiency can be kept around 70% , and can be …
