- Circuit extends battery lifeJaime Castelló José María Espí Rafael García-GilTwo 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...Jun 8, 2023
- Isolated-FET Pulse Driver Reduces Size, Power ConsumptionJaime Castelló José María Espí Rafael García-GilThree-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...Mar 30, 2022
- Isolated FET pulse driver increases power rate and duty cycleJaime Castelló José María Espí Rafael García-GilIn 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...Mar 3, 2022
- Circuit adds foldback-current protectionJosé María Espí Rafael García-GilFor 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...Nov 5, 2021
