Two previous Design Ideas describe simple ways to automatically disconnect a battery from its load after a preset on period, which extends battery life (references 1 and 2). These circuits have little loss in...

Three-phase controlled rectifiers and inverters, matrix cycloconverters, and cascaded power stages typically comprise large numbers of power transistors, each with its own driver circuit. The circuit in Figure 1...

In power converters, pulse-drive circuits transmit the pulses a controller generates to the power transistor. Driver circuits must both transmit the controller's switching on/off signals with galvanic isolation and...

For many applications that require power-supply currents of a few amperes or less, three-terminal adjustable-output linear voltage regulators, such as LM317, offer ease of use, low cost, and full on-chip overload...
