High-voltage DC capacitors are designed to handle and store significant amounts of direct current (DC) voltage, making them crucial for applications requiring stable, efficient energy storage and regulation. Our range of high-voltage DC capacitors provides superior performance, with robust construction.
In electric vehicle (EV) applications, DC link capacitors help offset the effects of inductance in inverters, motor controllers, and battery systems. They also serve as filters that protect EV subsystems from voltage spikes, surges, and electromagnetic interference (EMI). Figure 1.
II. THE BUS LINK CAPACITOR’S ROLE The bus link capacitor is used in DC to AC inverters to decouple the effects of the inductance from the DC voltage source to the power bridge. Figures 1A and 1B show two examples of a typical hard switched pulse width modulated (PWM) inverter that converts DC voltage to a three phase AC voltage.
Another EV subsystem where DC link capacitors are found is the inverter in motor drive circuits (shown in Figure 3). The inverter converts DC power from the battery to three-phase AC power to drive the traction motors during acceleration, and then converts AC power back to DC during braking.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
