PF Test Equipment
A transformer ratio-arm bridge circuit is utilized as depicted in the simplified diagram of Figure 1. The circuit comprises a standard reference capacitor (CS) and the insulation under test (CX). A distinctive feature of the circuit is a specialized multi-winding...
Simple buck mode switching regulator circuit diagram
This is a simple buck mode switching regulator circuit diagram. This circuit is more efficient; switch mode regulators convert DC input voltage to pulses of high DC voltage. The DC pulses are used to charge a storage capacitor to the...
CF1 CF2 main circuit
AC voltage is rectified by a bridge (VD1-VD4). A resistor (R1) limits the buck, while diode (VD5) provides clipping. A trapezoidal wave is generated as the trigger circuit for DC voltage and synchronization. When the base of transistor (VT1) receives...
amp variable output switching regulator lm195
This circuit is a variable output switching regulator designed for general-purpose applications. An LM105 positive regulator serves as the amplifier-reference for the switching regulator. Positive feedback to induce switching is derived from the LM105 at pin 1 through an LM103...
LCD power supply circuit
The following figure's switching regulator generates a negative voltage from the notebook battery supply. The microprocessor data bus drives a 4-bit DAC (74HC273), which can vary the regulator output between 6.5 to 11.5 V. This arrangement enables a staircase of...
Doubling rectifier circuit in negative ion generator application circuit
Doubling rectifier circuit in a negative ion generator application circuit.
